Abstract:

Taking velocity moment as controlled variable, the formulas were deduced to calculate quasi 3D inverse problem for uniform stream model of guide pulley. According to the theory of two relative flow surfaces and the force analysis of air bubble, the formulas were deduced to calculate quasi 3D direct problem while gas and liquid running in the guide pulley of multiphase pump, and a method was provided to carry on quasi 3D numerical calculation of inner flow filed. Furthermore, the quasi 3D inverse problem was calculated and the primary design of vane shape for guide pulley was developed. Based on the calculated result, the flow state of guide pulley was analyzed. The analysis results show that quasi 3D method is efficient and viable to be used to solve direct problem and inverse problem of guide pulley for multiphase pump.
