To identify the spatiotemporal coherent structure of compressor tip leakage flow, spectral
proper orthogonal decomposition (SPOD) is performed on the near-tip flow field and 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 …

The influence of the moving endwall on the behavior of the tip leakage flow in compressors
holds substantial significance. This work investigates the unsteadiness of the compressor's …

Based on the scale-adaptive simulation, the interaction mechanism between the tip leakage
flow (TLF) and the inlet boundary layer (IBL) and its effects on the tip flow field and …

The spike-type rotating stall in axial compressor is one of the major causes for the
aeroengine failure. The evolution of the flow structures, especially in the rotor tip region, is …

Rotor tip clearance (TC) shows significant effects on the stability and performance of aero-
engine compressors. TC is also related to the producing of noise and tip leakage flow which …

As a critical factor affecting compressor performance, the influence of a rotor-stator axial
clearance on rotating stall characteristics remains unclear. In the process of understanding …

Unsteady flow is highly related to flow loss and aerodynamic performance degradation in
the axial compressor. In this paper, the dynamic mode decomposition method was used to …

The tip clearance size has historically been considered to be the main factor affecting
stability range in axial fan and compressors. This paper reveals that the stall characteristics …

Steady and unsteady CFD predictions of a state-of-the-art 11-stage axial compressor
performances are compared with measurements and scrutinized to determine their ability to …
