Influence of compressor rotor blade tip squealer on performance
Blade tip squealer can improve partial performance,efficiency,and pressure ratio of the impeller,which has been widely applied to compressor blades of aero-engines and gas turbines.The middle stage blade of the high-pressure compressor of a high bypass ratio turbofan engine was taken for numerical simulation,applied with different blade tip squealers,in order to investigate the aero performance change affected by different squealer depth,height,and width.The simulation results reveal that the blade tip squealer has a positive influence on the aero performance of compressor.Meanwhile,the deeper and the longer the squealer is,the better aero performance the blade would gain.
