An aerodynamic instability known as stall occurs in axial compressors as the mass flow rate
is reduced and the blade loading reaches its limit. At this limiting condition, an easily …

The objective of this work is to develop and test a set of general guidelines for choosing
parameters to be used in the state-of-the-art actuator line method (ALM) for modeling wind …

This paper reviews modelling and interpretation advances of industrial fan stall phenomena,
related stall detection methods, and control technologies. Competing theories have helped …

Pressure and velocity fluctuations characteristics of tip clearance flow in the rotor and stator
of the axial compressor are studied by large eddy simulation (LES) at the near stall …

Turbomachinery plays a vital role in energy conversion systems, with aerodynamic issues
being integral to its entire lifecycle, spanning the period of design, validation, and …

Experimental and numerical studies were conducted to investigate tip-leakage flow and its
relationship to stall in a transonic axial compressor. The computational fluid dynamics (CFD) …

In order to investigate the effect of impeller tip clearance on internal flow fields and the
rotating stall inception impacted by tip leakage vortex and inlet unsteady flow in a mixed-flow …

Numerical investigations were conducted to predict the performance of a transonic axial
compressor rotor with circumferential groove casing treatment. The Notre Dame Transonic …

The growing demand for alternative technologies, of clean and sustainable nature, has
