Abstract
A recently developed, time-accurate multigrid solver has been used to investigate the capability of predicting trailing edge vortex shedding by means of the Reynolds-Averaged Navier-Stokes equations and algebraic turbulence models. The study has been performed on a turbine stator blade for which experiments have recently been carried out. Calculations using a mixing-length based model for turbulence closure indicate the inception of shedding even on relatively coarse trailing edge (C-type) grids.
