... casing treatment Computational fluid dynamics (CFD) is being widely used to simulate the flow in turbomachines [ 1 – 4 ]. Reynolds-averaged Navier–Stokes (RANS) simulations with different closure models for the Reynolds stresses are the most popular due to the low computational cost. Questions...

.... A separation of the rotor suction side boundary layer is also observed at near stall conditions. Then, two approaches are tested in order to control these flows in the tip region. The first one is a casing treatment with nonaxisymmetric slots. The method showed a good ability to control the tip leakage flow...
