Abstract:The mathematical model of pneumatic drying of polycarbonate material in vertical tube was established based on particle dynamics and Eulerian multiphase fluid model. The numerical solution of the model showed a good agreement with experimental data obtained from polycarbonate pilot production on particle moisture and air humidity along the length. Analyses of influencing factors of gas inlet temperature, gas velocity and particle size on moisture of polycarbonate material along tube length were given. The distributions of radial parameters of gas velocity and particle temperature were illustrated. The model can be used for further investigation of the drying of particulate material of industry.
