Rotating Stall in a Radial Vaneless Diffuser

Journal of Basic Engineering, 1964
This paper is concerned with the theoretical and experimental aspects of unsteady flow in a radial vaneless diffuser. Specifically, the appearance of self-excited oscillations of large amplitude is investigated in great detail. The waves appear when the angle between the tangential and total velocity becomes very small.

Rotating stall in variable geometry compressors

2016
The design and operation of gas-turbine engines is heavily influenced by the off-design stability of the compressor, which limits obtainable performance and may result in aeroelastic vibration issues. Whilst Variable Stator Vanes (VSVs) are widely used to mitigate this problem, research considering the mismatching effect of VSVs away from their optimal

Rotational Stall in a Mixed-flow Pump

The numerical results used to describe the special flow features/characteristics of the mixed-flow pump in this chapter were obtained by employing the computational methodology described in Chapter 3 which includes the pump model, mesh generation, turbulence models and their near wall treatment, and the boundary conditions.
