Tip Leakage in a Centrifugal Impeller

Journal of Turbomachinery, 1989
The effects of tip leakage have been studied using a 1-m-dia shrouded impeller where a leakage gap is left between the inside of the shroud and the impeller blades. A comparison is made with results for the same impeller where the leakage gap is closed. The static pressure distribution is found to be almost unaltered by the tip leakage, but significant

Tip leakage reduction through tip injection in turbomachines

22nd Joint Propulsion Conference, 1986
This paper descr ibes an experimental s tudy on t i p leakage flow reduct ion through t i p i n j e c t i o n . A s i n g l e blade was placed i n the test s e c t i o n of a wind-tunnel wi th a gap between the t i p of t h e blade and t h e top w a l l .

Effect of arbitrary blade tip design on tip leakage flow

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2019
Tip geometry modification is frequently used to suppress the tip leakage flow in the turbine cascade however a universally beneficial tip geometry modification design has not been fully discovered. In this paper, the two-surface coupling arbitrary blade tip design method in three-dimensional physical space which satisfies the simple trigonometric ...
