Simulation of rotating stall by the vortex method

Journal of Propulsion and Power, 1985
The vortex method, coupled to a boundary-layer solver, is applied to the numerical simulation of high Reynolds number incompressible flow in two-dimensional cascades. Periodic conditions are imposed along the plane of the cascade, with several blades per period. Good agreement is found with two finite-difference methods for a single-blade case.

Dämpfung von Rotating Stall in Radialverdichterstufen

Vakuum in Forschung und Praxis, 2001
Radialverdichter neigen im Teillastbereich zu rotierendem Ablosen der Stromung im Laufrad, das oft zu transienten Druckschwingungsvorgangen und zum "Pumpen" des Verdichters fuhrt. Betriebszustande im Teillastbereich mit transienten Vorgangen mussen vermieden werden, da sie den Verdichter und die Anlage durch Schwingungen gefahrden konnen.

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.

A cascade tunnel for investigation of rotating stall

1954
A test apparatus which will reproduce the rotating stall phenomenon found in axial compressors has been constructed and installed in the main wind tunnel circuit of the Gas Turbine Laboratory. The test section consists of a two dimensional, circular, radial outflow cascade between two flat plates.
