Abstract

In this research, the FILM COOLING through multiple squired cross section cold jets inclined normally into a hot cross flow are computationally simulated. The turbulence effects are modeled using the RANS approach applying the `v2¦-kw, Standard k-w and the SST turbulence models and the obtained results are compared. The governing equations of the mass conservation, momentum and energy are discreted and solved using the FINITE VOLUME METHOD and the SIMPLE algorithm over a structured, non-uniform multi-block grid. The jet into cross flow velocity ratio and the jet Reynolds number are 0.5 and 4700 respectively. The results show that the `v2¦-kw model predicts the complicated structures of the flow more accurately, in comparison with the k-w and the SST models.
