0611 Numerical Investigation on Tip Leakage Vortex Control of Turbine Rotor by Tip Injection

Abstract

In a compressor and a turbine blade passages ， there exist a number of vorticies such as horseshoe vortex and passage vortex ， They lead to large loss ． Tip leakage vortcx is one ofsuch vorticies ， and accounts 負 )r about 30％ ofaH loss in a
