Mechanism in Pneumotransport of the Fibroid Substance

摘要: 本文对纤维状物料的气力输送机理进行了探讨.文中将物料对空气的相对运动看作为空气在松散纤维状物料群体所组成的多孔介质中的渗流问题.由此推得的理论结果与以往所测的实验数据比较,大致符合.

Abstract: In this paper,the mechanism of pneumotransport of the fibroid material is discussed.It is thought that the motion of air relative to the material is the filtration of the air passing through the porous medium which is composed of the cluster of fibroid material.It is found that the deviations of the experimental data with the theoretical results are within experimental error.
