Unsteady Reynolds Averaged Navier Stokes (URANS) simulation of film cooling jets in a cross-flow with an improved k-tau model is presented in this work. The improved model is able to reproduce the unsteady behavior of key flow structures like the horse-shoe vortex as well as demonstrates improved predictions of the vertical and lateral spreading of the film cooling jet. However, the anisotropy of the flow is not captured accurately by the Bousinesque approximation of the Reynolds stresses employed in the model and is therefore identified as a major area of improvement in the next stage of the model development.
