流体中颗粒物在外力作用下运动速度模型的探讨 The Velocity Model of Fluid Particulate under External Force

On the assumption that the particulates are spherical and the fluid is under laminar conditions, the basic ve- locity model is deduced for the fluid particulate under external force at any moment by mathematical means, and the specific velocity models are further inferred in the effects of gravity, centrifugal and static electricity. It has instructive meaning in helping students understand in class and apply the theory to practice, although it is obtained under ideal conditions. Furthermore, the kinematic velocity of fluid particulate is a major parameter in designing the related dust catcher and sedimentation basin in water and air pollution control, so the study of the velocity model of fluid particulate can redound the application value in actual engineering design.
