Ergun Software exists in two independent pakages Ergun BFB is dedicated to the modeling, Design and Expert Analysis of Bubbling Fluid Beds and their peripherals (grid, cyclone, heat exchanger, chemical reaction, etc.). In addition to the calculation modules, the pack includes a number of extra tools like a “Gas/Solid Database” for the preparation of data files (see environment), a “Video Show” and a “Slide Show” for training purposes. A complete illustrated case is treated in the “Tutorial”. A “Virtual Expert” helps the user at each step of the design study. Ergun CFB is dedicated to the Modeling, Design and Expert Analysis of Circulating Fluidized Beds and their peripherals (grid, cyclone, siphon, heat exchanger…). The program offers a number of the latest modeling methods for diverse aspects of a CFB design and study : “Flow Pattern”, “Highly Charged Cyclones”, “Pressure Equilibrium Diagram”, etc. In addition to the modeling of the above items, the software provides an impressive tool for the modeling of a complete CFB system with secondary air (if any) and population balance. The pack includes the famous Ergun “Gas/Solid” Database with all its features. Ergun Fluization Technology -

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-
