Effect of Film Position on the Flow and Heat Transfer Characteristics of Full-Ribbed Rotor Tip
Frontiers in Energy Research, 2022 This article numerically studied the flow and heat transfer characteristics of the full-ribbed fluted tip of a rotor with four types of distribution of cooling films, namely, the mid-arc uniform film at the bottom of the groove, the uniform film on full ...

Tip-Leakage Vortex Inception on a Ducted Rotor [PDF]
, 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

Investigation on the Mechanism and Parametric Description of Non-Synchronous Blade Vibration
Entropy, 2021 In order to explore the mechanism during the process of the non-synchronous vibration (NSV), the flow field formation development is investigated in this paper. Based on the fluid–structure interaction method, the vibration of rotor blades is found to be

The Role of Tip Leakage Vortex Breakdown in Compressor Rotor Aerodynamics [PDF]
Journal of Turbomachinery, 1998 The breakdown of tip leakage vortex has been investigated on a low-speed axial compressor rotor with moderate blade loading. Effects of the breakdown on the rotor aerodynamics are elucidated by Navier–Stokes flow simulations and visualization techniques for identifying the breakdown.

Investigation of the groove effect on the tip leakage vortex flow
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The groove effect on the tip leakage vortex around a NACA0009 hydrofoil was studied by numerical method. The results show that, as the groove angle is 45°, the groove could enhance the turbulence kinetic energy around the TLV, weaken the TLV strength and improve the pressure in the TLV core, resulting in an efficient suppression
