旋流闪急干燥器流场分析

摘要

在理论研究和实验分析的基础上，对旋流闪急干燥器旋转流场进行了研究.通过对理论式进行无量纲化，拟合得到了切向速度分布、轴向速度分布和沿程压力降的经验式.%The characteristics of swirling flow are studied in a spin flash dryer. On the base of the experiments, we imitated the tangential and the axial velocity expressions, and estimated the pressure drop along flow direction.
