Axial Flow Gas Mixing Pump And A Single Compression Level Of The Flow Field Calculation

The oil-gas transport pump, which serves as main tools for multiphase transport in oilfield, may both increase the product for developed oilfield and reduce the investment for developing oilfield . Therefore, more and more people give their attention to the research for this kind of pump and make it to be a hotspot in multiphase transport; the impeller, as one of the most important components in the pump, have significant influence on the performance of the pump, so the research to it have high significance.At first, the thesis introduced the status of this pump in oilfield, the existing condition at home and abroad and the theory of the two-phase flow. Utilizing the techniques of CFD, the flowfield of a stage of this pump is calculated and analyzed the result, so some opinions is given for improvement.All in all, the type of pump, such as 100-YQH,is a successful design, but there still are many thing to do.
