Numerical simulation of mass and heat transfer process in centrifugal fluidized bed

A mathematical model of the heat and mass transfer characteristics of wet materials in a drying process in a centrifugal fluidized bed (CFB) dryer is developed. In this model, the drying material is simplified as ideal little balls of potato. Under different conditions of gas temperature and relative humidity of inlet gas, rotating speed of fluidized bed and superficial gas velocity, the mean relative wet content of the drying material is paper, a group of control equations that can be used to simulate the process of the heat and mass transfer of the granule materials inside of CFB is given and proved.
