摘要：
Cavitation is a key factor to influence the efficiency and safety of hydraulic machinery, so characteristic and mechanism of cavitation, and how to improve the cavitation phenomenon are still the issues that a lot of experts pay attention to and research. In this paper, based on changing hydrofoil structure, that is drilling holes near the smallest pressure point on the back of hydrofoil and altering the radius of hole, then the effect of hole and aperture on flow field are analyzed. The result can be reference for improving cavitation of fluid machinery. (C) 2011 Published by Elsevier Ltd.
