【摘要】 悬浮烘干机是一种新型的烘干设备,目前已在一些工厂投入使用。本文所研究的是该烘干机内的冷态流场,按照 Boussinesp 假说和混合长度理论,作者在对该流场进行了四项合理性假定的基础上,将雷诺方程简化为一个边值问题和一个初值问题。对此边、初值问题进行求解,得到了实测结果相吻合的理论计算结果。更多还原

【Abstract】 Suspension dryer,developed by us,is a new type of drying equipment which has conreinto use at a few plants.This Paper is concerned with the cold state flow field in the dryer.Ac-cording to the Boussinesq’s hypothesis and the mixing length theory,the authors simplify theReynolds’ equations as a boundary value problem and an initial value problem,based onfour reasonable assumptions for the flow field.The boundary value problem and the initialvalue problem are worked out numerically to obtain theoretical computations which are inconformity with experimental results.更多还原
