Computational tools for the analysis and design of
high-speed propulsors

Abstract:

Two methods for the analysis of cavitating blades are briefly described and applied to several propeller geometries. The results from the two methods are compared to each other and to those measured in experiments. Then, a cavitating blade design method is briefly described and applied to a case with given requirements and various imposed constraints.
