Description gas-liquid of current in flowing channel of electrical submersible pumps methods of computer modelling

Abstract

In this article updating of mathematical model of the centrifugal pump is offered. This model is necessary for calculation of dynamics of change of parameters of current of a multiphase mix in flowing channels of the pump. Numerical researches of parameters of biphase current are made. Transients on pressure and speeds of a liquid phase in elements of the centrifugal pump are constructed. The preliminary analysis of hydrodynamical currents in elements of Electrical Submersible Pumps on presence of unstable operating modes of the pump is made.
