The objectives of the paper are at first to formulate the applied mathematical/numerical model and at second to present some results from the validation study of thermally stratified flow over an isolated 2D–hill test case. The mathematical model is based on system of RANS equations closed by a two–equation high–Reynolds number k–ε turbulence model. The finite volume method and the explicit Runge–Kutta time integration method are utilized for numerical procedure.
