Abstract

The flow in a transonic rotor cascade is investigated by both experimental and numerical methods. Measurements include pressure profiles on the blade, total pressure profiles in the blade vane, boundary layer and wake profiles. Computations are performed by two different solvers with different turbulence models and three different transition models. Results indicate that the indroduction of transition models is necessary to have a realistic description of the flow field. Transition is shown to affect also the blade pressure distribution and shock strength mostly on the pressure side boundary layer. Experiments indicate the presence of trailing edge vortex shedding which is not captured by the steady computations. The transition models seem to be adequate for predicting the shock -boundary layer- interaction which induces a small flow separation on the suction side
