Optimal film cooling design often involves substantial costs associated with geometric modeling and simulation. Film cooling models offer an efficient alternative by simulating film cooling effects without the need to mesh the cooling structures. This study investigates two widely applied film cooling methods: the source term method and the virtual boundary method, both implemented in our in-house solver. To verify the models, we employ a cylindrical film cooling flat plate, evaluating the accuracy of the predictions through cooling efficiency metrics and contour maps. Additionally, we analyze the mesh sensitivity of both methods. The predictive performance of the models is validated against experimental results and compared with case where the cooling holes are fully resolved. The numerical results demonstrate that both models can accurately predict the downstream behavior of film cooling holes using a coarse grid, while maintaining good agreement with experimental data.
