Abstract

FILM COOLING has many applications such as in the gas turbine blade cooling, where inholes are introduced in the blades from which the cooling fluid are injected to the main stream covers the blade surface. In this research, turbulent three-dimensional FILM COOLING over a flat plate is numericallying investigated. Reynolds-averaged Navier-Stokes approach is applied for the simulations, using the standard k-e and shear stress transport models. Also, the simulations are performed using LARGE EDDY SIMULATION approach with the Smagorinsky subgrid scale model The FINITE VOLUME METHOD and the SIMPLE algorithm are applied in both simulations and the spatial and temporal terms are discretized using the power-law and the Crank-Nicolson schemes, respectively. At 90° injection angle, the results are compared with previous experimental and numerical results showing close agreements. Optimum values of velocity ratio and injection angle are obtained using the FILM COOLING effectiveness Parameter…
