Effects of casing motion on tip leakage flow and film-cooling effectiveness of squealer tips
Journal of Thermal Science and Technology, 2017 A comparative investigation of leakage flow and film-cooling characteristics on different squealer tips is conducted under the conditions of stationary and moving casing. Firstly, the numerical method used in the calculations has been verified. Then, the

Desensitization of Tip Clearance Effects in Axial Flow Turbines
Journal of Fluid Science and Technology, 2010 The present study aims to control the leakage flow and total pressure loss in high pressure turbines. A new tip shape is proposed. It is based on the triple squealer shape by adopting a new middle squealer, along the camber line, whose first and last ...

Effect of impeller tip clearance on cavitation in an axial-flow pump
Engineering Science and Technology, an International JournalCavitation in axial-flow pumps reduces efficiency, induces noise and vibration, and causes wear on metallic components. The existence of a tip clearance, coupled with the high rotational speed of the impeller, creates a favorable condition for cavitation
