Numerical Spray Model of the Fluidized Bed Coating Process

摘要: In this study, a new model for the batch top-spray fluidized bed coating process is presented. The based on one-dimensional (axial) discretization of volume into different control volumes, in which dynamic heat and mass balances air, water vapor, droplets, core particles, material were established. coupling droplet phase's transfer terms with gas solid phases was established by means submodel trajectories individually simulated. calculation method combines Monte Carlo technique simulation particle exchange first-order Euler's solving balances, enabling prediction both distribution thermodynamic behavior during operation. results validated using experimental two-dimensional spatial air temperature humidity distribution...
