Suppressing tip leakage vortex cavitation via squealer-hole composite tip

Physics of Fluids
Suppressing tip leakage vortex (TLV) cavitation in rotating machinery, such as propellers and turbines, plays a crucial role in reducing hydrodynamic noise, mitigating cavitation erosion, and enhancing operational stability. This study proposes a composite tip structure that integrates squealer rims with jet holes to suppress TLV cavitation in a ...

Reynolds stress measurements in a turbine tip leakage vortex

2014
An experimental study of the structure of turbulence in a tip leakage vortex was conducted in a large scale, linear turbine cascade. The study was performed in a cross sectional plane 0.96 of the axial chord length downstream of the blade leading edge. The cascade consisted of five blades with an aspect ratio of one and an axial chord of 235.2 mm.

Study Tip Leakage Vortex of CPU Fan with Skewed Rotors

2013
In this chapter, to obtain the characteristics of tip leakage vortex in the flow field of CPU fan with skewed rotor, the tip leakage flow fields are used to investigate the three fans with three kinds of circumferential skewed rotors, including the radial rotor, the forward-skewed rotor, and the backward-skewed rotor.
