Numerical study on the design error stabilities of 3-dimensional streamline curvature inverse method for centrifugal impellers. Tian Xiaopei & Shan Peng Journal of Aerospace Power, 31(5):1159–1169, 2016.
abstract   bibtex   
Two groups of the high speed centrifugal impellers were both designed by the 3-dimensional streamline curvature inverse method and a quasi-3-dimensional inverse method with a slip factor model.One group had different blade numbers,while the other group had different total pressure ratios.The impeller performances were predicted by a commercial computational fluid dynamics(CFD)solver.The design error stabilities of the two methods were compared.The impacts of the splitter blades on the design errors were also studied. The results showed that the 3-dimensional streamline curvature inverse method could realize aproper adjustment to the blade shape according to the blade loading.And compared with the quasi-3-dimensional inverse method,the total pressure ratios of the impellers designed by the 3-dimensional streamline curvature inverse method were generally higher.Therefore, with the increase of blade loading,the design errors of the 3-dimensional streamline curvature inverse method changed much smaller than those of the quasi-3-dimensional inverse method;namely,the design error stability of the 3-dimensional streamline curvature inverse method was much better.In addition,for the quasi-3-dimensional method,the impacts of the splitter blades on the blade design results were much smaller.
