It remains one of Rocscience’s best selling programs. Now,Unwedge 3.0 builds upon the simple data entry and visualization capabilities of the old version - it’s analytically more sophisticated and easier to use. Unwedge 3.0 solves difficult wedge stability problems using a combination of block theory and stress analysis, and provides quick answers for engineers with no time to spare. With its leading edge science and major interface enhancements, a typical wedge analysis can now be performed with Unwedge 3.0 in less than 30 minutes. [/TD] [/TR] [TR] [TD=colspan: 3] [Hidden Content] [/TD] [/TR] [TR] [TD=colspan: 3, align: left]Recently, we sat down with Brent Corkum and Warren Stevens from the Unwedge 3.0 development team, and asked them to explain how Unwedge 3.0 will make life easier for geotechnical engineers.RocNews: So gentlemen, what exactly are the top improvements in Unwedge 3.0?Brent: That’s a tough one, because we’ve added a lot - improvements to both its analytical capabilities and its look and feel. But the new Windows based interface is up there – it’s really going to simplify both the analysis and design procedure. We’ve also focused on improving the design capabilities of the software. We’ve added better support models for bolts and shotcrete, the ability to optimize tunnel orientation and to look at different combinations of joints sets forming tetrahedrons from more than three joint sets. Plus, Unwedge 3.0 uses a completely new analysis engine based on Goodman and Shi's block theory, and includes the ability to analyze induced stress around the excavation and the effect on stability. There are new strength models such as Barton-Bandis and the Power Curve, and improvements to the way users can scale and size wedges.Warren: The new interface is definitely going to be the first thing users notice: we’ve got clipboard support and nicer graphics this time around. Editing support is also much easier; for example, joint combinations can be easily changed using a spin control. For the case of multiple joints, every possible combination can be analyzed very quickly using the new Combination Analyzer. There’s a new Integrated Stress Analysis feature, and the Tunnel Axis Plot shows how results change as tunnel orientation changes.[/TD] [/TR] [TR] [TD=colspan: 3] [Hidden Content] Analyzer dialog [/TD] [/TR] [TR] [TD=colspan: 3, align: left]RocNews: What kind of projects will particularly benefit from these enhancements?Warren: Unwedge 3.0 is particularly useful in projects where stress is thought to influence wedge stability, or where you need to analyze a lot of tunnel orientations. An example would be a curving tunnel or spiral ramp. Unwedge 3.0 is also helpful in finding the worst case for any tunnel orientation, any combination of multiple joints, or where tunnel orientation can be changed in order to minimize support costs. Another major improvement is in report generation; now users can create better-looking reports in less time.Brent: Projects that will most benefit from this version include those with wedges formed around drifts and shafts in underground mining, projects where wedges have formed around transportation tunnels, and projects where wedges have formed around underground power or pumping stations.[/TD] [/TR] [TR] [TD=colspan: 3, align: left][Hidden Content] Analysis Option - normal stress contours on wedge planes[/TD] [/TR] [TR] [TD=colspan: 3, align: left]RocNews: Which Unwedge 3.0 interface enhancements will be most helpful to users on a daily basis?Brent: The ability to easily input and analyze both the wedge geometry and the tunnel support system - that's a big one. We've made good use of OpenGL in this version - I think users will appreciate the new graphics that use shading and transparency to visualize both the wedges and tunnel. In general, user interaction is much more interactive, and therefore, a lot simpler to use. Things like the ability to drag wedges along their respective failure direction. Using Tooltips and the Wedge Information pane, users can easily extract just about any analysis information, such as areas, volumes, safety factors or failure modes that they want. Support systems can be easily designed using interactive placement of the support; for example, property definition is based on available bolt and shotcrete systems, making it easy for customers to choose their support system.Warren: I think Clipboard Support is going to prove very helpful - you can generate screen captures for reports very easily, as opposed to the more time consuming method in the older DOS version. For me, that would reason enough to upgrade - it looks nicer and saves a lot of time. That, and the ability to change joint combinations using a spin control - another huge timesaver.[/TD] [/TR] [TR] [TD=colspan: 3] [Hidden Content] Wedge Movement and Data Tips [/TD] [/TR] [TR] [TD=colspan: 3, align: left]RocNews: You indicated that there are a significant number of analytical improvements. Which ones will be most helpful to the typical user?Brent: I'm glad you used the word "typical", because that's what I want to stress to readers. All of these improvements, interface or analytical, have been created based on feedback we've gotten from working engineers. We're constantly asking them, and ourselves, "We think this is a great feature, but will it get used?" The new analysis techniques we've added to version 3 don't just widen the scope of the program, they improve the accuracy of the results. Using Goodman and Shi's block theory, the computation of the perimeter wedges is quicker and more accurate. Plus, an entirely new calculation algorithm was developed for finding and determining the size of possible end wedges. We've also added new bolt models, including cable bolts, grouted dowels with variable grout length, swellex and split-set, and users can now simulate multiple layers of shotcrete with different properties. All these features will greatly improve the accuracy of analysis results.[/TD] [/TR] [TR] [TD=colspan: 3, align: left][Hidden Content] placement of bolt patterns[/TD] [/TR] [TR] [TD=colspan: 3, align: left]Warren: (laughs) Gee Brent, I forgot how much we actually put in there. I think that the most significant, previously unavailable feature is Integrated Stress Analysis. Many of Unwedge 3.0's improvements are "time-savers"; they're interface enhancements that make the program more intuitive and easier to use. But new analytical tools like Integrated Stress Analysis are not only easy to use, they also give users the ability to do more complex, more useful analyses on the effect of stresses around an excavation.Brent: Actually, I forgot to mention pseudo-static seismic modeling; that's in there too. A two-dimensional complete plane strain boundary element model has been added to the program to determine stress effects on the stability of the wedges. Scaling of wedges now accurately reflects the values you define for trace length and persistence. Unlike Unwedge 2.3, which used the trace length values you defined as approximate measures, Unwedge 3.0 accurately accounts for trace lengths. The program will also try to determine the maximum volume wedge with the trace lengths you define.[/TD] [/TR] [TR] [TD=colspan: 3, align: left][Hidden Content] Properties dialog[/TD] [/TR] [TR] [TD=colspan: 3, align: left]RocNews: Sounds like you were kept pretty busy on this version. As developers, what was your biggest challenge with Unwedge 3.0?Warren: Well, right off the bat we knew we were moving away from 2.3's DOS interface, so deciding on the graphical user interface components of the program was time consuming. It's always a challenge to organize your features and make them intuitive to users - stuff like the screen layout, the view management, the toolbar switching and the sidebar. I'm proud of the result - I think it looks good. Also, like Brent mentioned earlier, we learned some new tricks and used them to make the interface richer looking.Brent: The whole thing was a challenge, especially since we wanted to release the software this year, and we'd already spent a good part of it working on the newest version of Slide. But in the end, we completely redesigned Unwedge - from both an analysis and interface perspective. It had to be completely rewritten and the user-interface had to be completely redesigned. And, despite how busy we were, we also added functionality based on some customer requests. They were good ideas, so we felt it was important to incorporate them into the new release.[/TD] [/TR] [TR] [TD=colspan: 3, align: left][Hidden Content] Support Pressure versus Tunnel Axis Orientation[/TD] [/TR] [TR] [TD=colspan: 3, align: left]RocNews: Speaking of our users, any final advice to Unwedge 3.0 users on how they can get the most out of this version?Warren: For beginning users, keep your initial analysis simple and build up the complexity gradually. I encourage this modeling methodology so that you properly understand the different mechanisms of the analysis, such as support and stress effects. For more advanced users, remember to use the Combination Analyzer and the Tunnel Axis Plot - the analysis of multiple orientations used to be manual, now it's automated. This will save you a lot of time. And take advantage of the new Integrated Stress Analysis module.Brent: My advice for newer users is to use the toolbar buttons to switch to the different views, and take note of the view-dependent controls that appear in the side bar. For most tasks in this program, you'll benefit by starting this way. For more experienced users, I think they'll find that with the easier to use interface and the new functionality, you'll be able to solve a broader range of problems, in less time. Come to think of it, I think all users will appreciate that - after all, time is money.[/TD] [/TR] [TR] [TD=colspan: 3, align: left]RocNews: I think that’s a good final thought to end on guys. Brent, Warren – thanks for your information and insight on Unwedge 3.0.[/TD] [/TR] [/TABLE]

HEAT BALANCE OF THE VACUUM DISTILLATION COLUMN – KEY FOR IDENTIFICATION OF THE REASON FOR LOW HEAVY VACUUM GAS OIL YIELD Dicho Stratiev, Ivelina Shishkova, Petya Dermatova Lukoil Neftochim Bourgas – R&D Department, 8104 Bourgas, Bulgaria, Abstract Estimation of heat balance of the vacuum distillation column of atmospheric resid in the Lukoil Neftochim Bourgas identified the reason for a decrease in the heavy vacuum gas oil yield. The hypothesis of a leakage of the heavy vacuum gasoil draw tray was rejected and it was found that the hydraulic resistance in the heavy vacuum gas oil pump around did not allow an increase of its flow rate and taking away the heat required for condensation of heavy vacuum gas oil, contained in atmospheric residue. دانلود

Sequential modeling of fluidized bed paddy dryer Navid Bizmark, Navid Mostoufi *, Rahmat Sotudeh-Gharebagh, Hossein Ehsani Multiphase Systems Research Lab., School of Chemical Engineering, University of Tehran, P.O. Box 11155/4563, Tehran, Iran Abstract A sequential method was developed to model a continuous plug flow fluidized bed dryer. The method is based on dividing the dryer into sections in series with ideal mixing for both solid and gas phases in each section. In order to determine the proper number of sections, drying experiments were carried out using paddy at different operating conditions. It was shown that the number of sections can be correlated to Damköhler number, which includes kinetic and hydrodynamic parameters of the process. The model is able to predict the particle’s moisture profile along the bed as well as the moisture content of dried product. It was shown that the model fits the experimental data satisfactorily with the correlation coefficient of 0.989. Moreover, the model was tested against available data in the literature at different scales and operating conditions for which an error of less than 4.5% was observed in predicting the paddy moisture content at the outlet. دانلود

Review of solar dryers for agricultural and marine products A. Fudholi *, K. Sopian, M.H. Ruslan, M.A. Alghoul, M.Y. Sulaiman Solar Energy Research Institute, Universiti Kebangsaan Malaysia, 43600 Bangi Selangor, Malaysia Abstract Drying for agricultural andmarine products are one of themost attractive and cost-effective application of solar energy. Numerous types of solar dryers have been designed and developed in various parts of the world, yielding varying degrees of technical performance. Basically, there are four types of solar dryers; (1) direct solar dryers, (2) indirect solar dryers, (3) mixed-mode dryers and (4) hybrid solar dryers. This paper is a review of these types of solar dryers with aspect to the product being dried, technical and economical aspects. The technical directions in the development of solar-assisted drying systems for agricultural produce are compact collector design, high efficiency, integrated storage, and long-life drying system. Air-based solar collectors are not the only available systems. Water-based collectors can also be used whereby water to air heat exchanger can be used. The hot air for drying of agricultural produce can be forced to flow in the water to air heat exchanger. The hot water tank acts as heat storage of the solar drying system.

Drying of hot chilli using solar tunnel drier M.A. Hossain a,*, B.K. Bala b a Farm Machinery and Postharvest Process Engineering Division, Bangladesh Agricultural Research Institute, Gazipur-1701, Bangladesh b Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh Received 28 July 2004; received in revised form 9 June 2006; accepted 9 June 2006 Available online 24 August 2006 Communicated by: Associate Editor Istvan Farkas Corresponding author * Abstract A mixed mode type forced convection solar tunnel drier was used to dry hot red and green chillies under the tropical weather conditions of Bangladesh. The drier consisted of transparent plastic covered flat-plate collector and a drying tunnel connected in series to supply hot air directly into the drying tunnel using two fans operated by a photovoltaic module. The drier had a loading capacity of 80 kg of fresh chillies. Moisture content of red chilli was reduced from 2.85 to 0.05 kg kg1 (db) in 20 h in solar tunnel drier and it took 32 h to reduce the moisture content to 0.09 and 0.40 kg kg1 (db) in improved and conventional sun drying methods, respectively. In case of green chilli, about 0.06 kg kg1 (db) moisture content was obtained from an initial moisture content of 7.6 kg kg1 (db) in 22 h in solar tunnel drier and 35 h to reach the moisture content to 0.10 and 0.70 kg kg1 (db) in improved and conventional sun drying methods, respectively. The use of a solar tunnel drier and blanching of sample led to a considerable reduction in drying time and dried products of better quality in terms of colour and pungency in comparison to products dried under the sun. The solar tunnel drier and blanching of chilli are recommended for drying of both red and green chillies. Drying of hot chilli using solar tunnel drier.pdf

Modelling of sugar drying in a countercurrent cascading rotary dryer from stationary profiles of temperature and moisture K. Rastikian a, R. Capart a,*, J. Benchimol b a Departement de Genie Chimique, Universite de Technologie de Compiegne, CNRS-UPRES-A-6067, BP 20529-60205 Compiegne Cedex, France b SAINT LOUIS SUCRE, Centre de Recherches, 27550 Nassandres, France Corresponding author * Received 19 November 1998; accepted 24 May 1999 Abstract From the shape of stationary pro®les of temperatures and moisture for the gas and solid phases, two distinct zones clearly appears in a counter-current cascading rotary dryer of sugar; a ®rst zone in which the drying takes place, a second zone in which the dried sugar is reheated by contact with the entering hot air. The ®t of experimental data of temperature and humidities was used to test a mathematical model for the drying zone and to ®nd optimal values of heat and mass transfer coecients. Additional investigations at laboratory scale have provided information on the kinetics of drying of sugar crystals falling in a curtain as in the airborne phase of a rotary dryer. Sorption isotherms show that a strong re-moistening or deliquescence of sugar occurs at about 80% relative humidity. Obviously such a value must not be reached in an industrial dryer.

Conventional and modified rotary dryer Comparison of performance in fertilizer drying E.B. Arruda, J.M.F. Fac¸ anha, L.N. Pires, A.J. Assis, M.A.S. Barrozo Federal University of Uberlândia, Chemical Engineering School, 38400-902 Uberlândia, MG, Brazil abstract In this work, the performance of a conventional cascading rotary dryer has been compared with a modified configuration, known as a roto-aerated dryer. The results obtained show that for the roto-aerated dryer the residence time was 48% lower, the difference between outlet- and inlet-solids temperature was 1.7–3.3 times higher and the air temperature variations were 1.1–1.7 times higher than for the conventional rotary configuration. All the results of the present work confirm the better performance of roto-aerated dryer. This improvement in drying performance is due to the better gas-particle contact in this new configuration.

Fabric-drying process in domestic dryers V. Yadav *, C.G. Moon Department of Mechanical Engineering, The University of Auckland, Auckland 1142, New Zealand Available online 4 September 2007 Abstract A theoretical analysis of the drying process occurring inside the household electric tumbler clothes-dryer is performed to determine various thermo-physical parameters affecting the energy consumption and for the development of a simulation model. Experiments are conducted on a test set-up, based on a compact tumble-dryer, to measure the values of the parameters necessary for evaluating the performance. Widely-accepted economy standards are considered for comparison of simulation and experimental results. The simulation results are in reasonable agreement with experimental data. An empirical correlation for the specific moisture-extraction rate (SMER) is developed to translate energy-consumption information from one standard to the other.
