Abstract

This paper introduces the designed calculation course of improvement of the mixed turbine impeller by applying computational aided design/computational fluid dynamics method for hydraulic machinery. Taking the HL220 turbine impeller as an example, the cavitation characteristic of the impeller inlet flow under the large flow was analyzed. Then, some approaches are presented to improve the performance of impeller inlet flow and cavitation by reshaping the blade. In addition, the method to determine the blade form for better cavitation characteristic and the relevant geometric parameter are also presented in this paper.
