Visualized observations of trajectory and dynamics of unsteady tip cloud cavitating vortices in axial flow pump

open access: yesJournal of Fluid Science and Technology, 2017
A large-scale perpendicular cavitating vortices (PCVs), at the trailing edge of attached cavitation on the blade suction side near the tip region, has been found recently due to the great impact on performance breakdown in an axial waterjet pump. However,

Influence of the tip gap size on the development of the tip-leakage vortex using Large Eddy Simulations

open access: yes, 2015
In hydraulic turbines, the tip-leakage vortex is responsible for flow instabilities and for promoting erosion due to cavitation. To better understand the flow in the tip region, LES computations are carried out to compute the flow around a NACA0009 blade

Tip-Leakage Vortex Inception on a Ducted Rotor

open access: yes, 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

Effects of cutback squealer tips on the vortices and local loss in the tip region of axial turbine rotor

open access: yesPropulsion and Energy
Tip leakage loss is a significant source of aerodynamic loss in the turbine rotor and can be controlled by using a cavity tip. In this paper, three configurations with cutback rims are numerically investigated to control the formation and development of ...
