摘　　要：采用CFD软件对离心式喷雾干燥过程进行了非稳态数值模拟,对比分析了颗粒液滴喷射前后干燥塔内的温度场和含湿量等参数分布及变化情况,研究了颗粒在塔内的运动轨迹及直径分布,研究发现,数值模拟的结果与试验结果的误差在5%以内,可信度高。The unsteady state numerical simulation of centrifugal spray drying process was studied using CFD software.Parameters such as the grade of temperature and the humidity in dryer before and after jetting droplets were analyzed,and the motion trajectories and diameter distribution of particles also were obtained.The numerical simulation results were approximate to the experimental values with the relative errors of less than 5%,so they are credible.
