Suppressing tip-leakage vortex cavitation by overhanging grooves

Experiments in Fluids, 2020
In the present paper, a new control method for tip-leakage vortex (TLV) cavitation is proposed. This method, which combines the effects of grooves and winglets, is made of overhanging grooves (OHGs) fitted at the tip of a hydrofoil. Experimental and numerical investigations are conducted to evaluate the performances of OHGs in terms of TLV cavitation ...

PIV Measurements of a Tip Leakage Vortex

SNAME 26th American Towing Tank Conference, 2001
The tip-leakage vortex occurring on a ducted rotor was examined using both three component Laser Doppler Velocimetry (LDV) and planar Particle Imaging Velocimetry (PIV). The vortex strength and core size were examined for different vortex cross sections downstream of the blade trailing edge. The variability of these quantities are observed with PIV and

Interaction mechanism between incoming vortex and tip leakage vortex breakdown of a compressor cascade

Physics of Fluids, 2023
Tip leakage vortex breakdown (TVB) is an important flow character that affects the performance of axial compressors. In this study, the interaction mechanism between incoming vortex (IV) and TVB is investigated to improve the performance of compressor cascade.

Numerical Study of Tip Leakage Vortex Around a NACA0009 Hydrofoil

Journal of Fluids Engineering, 2021
Abstract In the tip clearance flow, the dominant vortex is the tip leakage vortex (TLV), which has a significant impact on the hydraulic and cavitation performance of axial flow machineries. In order to reveal the impact mechanism of the gap size on the TLV, gap flows with two gap sizes, i.e., τ=0.2 (2 mm) and τ=1.0 (10 mm), are ...
