Study On The Slip Velocity Profile Of Settling Slurry In Horizontal Pipeline

When settling slurry flows in a horizontal pipe the mechanism that how water carries solid particles and the predicting method with which the velocity profiles and the hydraulic gradient of the slurry flow can be calculated have been being important problems to be solved to the experts and the scholars working in this researching field.The velocity profile of settling slurry in a horizontal pipe is an important problem and the slip velocity profile is one of the researching fields. On the basis of research results of the experimentals and combining with the actual testing process of slurry flow experimentals, the article analyzes the change in momentum, velocity ,both of solid particles and water and their mass related to momentum exchanging over the acceleration time and the theoretical analysis method and model are proposed to predict the velocity profile and the hydraulic gradient.So, the theoretical analysis of slip velocity is very important and correct the slip velocity is the emphasis problem in this article.
