چکیده مقاله:

Having accurate values of the parameters which mainly govern the industrial processes in hand is the key aspect to handle the process and optimize it. To deal with this challenge, some mathematical models had have been developed and modified to be epidemic. This Study aims to present the simulation of gas-solid flow in fluidized bed dryer. Numerical solution of twodimensional, axis-symmetrical cylindrical model for both phases is the base for this study. Some of the versatile parameters like inlet gas velocity and temperature, diameter and density of particles during drying process went under magnification and also challenges of heat transfer along the bed are investigated and discussed in details. Solid temperature in the center and surface positions which are greatly affected by time and results are also shown. At In the end, model outputs are compared with experimental data which shows reasonable agreement and good match.
