Inlet flow distortion is expected to play a major role in future aircraft architectures where
complex air induction systems are required to couple the engine with the airframe. The …

The evolution of unsteady vortex structures in the tip region of an axial compressor rotor is
investigated based on delayed detached eddy simulation. The vortex structures are …

The present paper provides a summary of investigations of the tip air injection, which has
been studied for over 30 years to extend the stall margin in axial flow compressors. The …

Flow instability is a common issue encountered by high-speed compressors when they
operate outside of their optimal range, especially in highly loaded compressors. This study …

Particle image velocimetry (PIV) measurements at varying resolutions focus on the flow
structures in the tip region of a water-jet pump rotor, including the tip-clearance flow and the …

The tip leakage vortex (TLV) cavitating flow in an axial flow pump was simulated based on
an improved shear stress transport (SST) k-ω turbulence model and the homogeneous …

The complex flow field in the tip region of a turbomachine rotor, including the tip leakage
flow and tip leakage vortex (TLV), has been studied for decades. Yet many associated …

Stereo particle image velocimetry measurements focus on the flow structure and turbulence
within the tip leakage vortex (TLV) of an axial waterjet pump rotor. Unobstructed optical …

A kind of foam metal casing treatment (FMCT) is proposed and experimentally tested on a
low-speed axial flow compressor in this work. Foam metal is a foam-like substance with a …

In compression systems, the stable operating range is limited by rotating stall and/or surge.
Two distinct types of stall precursors can be observed prior to full scale instability: the …
