The evaluation of the effect of gas content on the characteristics of a Centrifugal Pump

摘要

The effect of gas content on the changing ofhead of a centrifugal pump isresearched.The method of numerical hydrodynamic modeling is used for solving this problem.The using mathematical model is described.The results of the simulation of fluid flow,which are depended on the air content,are presented.The data on the changingof head and the termination of its work are obtained.
