The Behavior of the Casing Boundary Layer With the Presence of Tip Leakage Vortex

Volume 2A: Turbomachinery, 2018
Casing boundary layer effectively places a limit on the pressure rise capability achievable by the compressor. The separation of the casing boundary layer not only produce flow loss but also closely related to the compressor rotating stall. The motivation of this paper is to present a viewpoint that the casing boundary layer should be paid attention to

Unsteady effects of vortex interaction on tip leakage vortex breakdown and its loss mechanism

Aerospace Science and Technology, 2018
Abstract In an unshrouded high-pressure turbine, tip leakage flow causes a loss of efficiency. The loss mechanisms of tip leakage flow were investigated mostly with steady uniform incoming conditions in previous studies. This paper investigated the unsteady aerodynamic performance of the tip leakage flow in a turbine stage by solving Unsteady ...

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.
