A Theory of a Partially Cavitating Hydrofoil in Exponential Shear Flow.

Abstract

The rotors and stators of turbomachinery operate in partially cavitating condition in the case of high speed hydraulic machinery, and further they operate in various types of shear flows such as boundary layers, jets and wakes. This paper aims firstly to apply the existing theory for the two-dimensional supercavitating hydrofoil in exponential shear flow to partial cavitation and secondly to make it possible to clarify the effects of shear parameter on both cavitation and force characteristics of hydrofoil in the shear flow.
