摘要：

The k-epsilon turbulence model, liquid evaporating model, and ideal gas equation was The Lagrangian Particle Tracking multiphase model was used to calculation. The goal of this paper is to study pressure effect on the variation of averaged values of mean droplet diameter and droplet temperature in the spray dryer, as well as water drops as they travel through the spray dryer. Because the outlet pressure affect the reference pressure, and then affect the evaporating rate, so the drying rate, drying temperature.
