Abstract

Numerical investigations of turbine blade are carried out using large-eddy simulation (LES), Scale Adaptive Simulation (SAS), k-e with extended wall function, Spalart-Allmaras (SA), and Sheer Stress Transport (SST). The goal of the present studies is to investigate the turbine blade aerodynamics and blade cooling techniques. The simulations are performed for a Reynolds number, Re=3.67x10^6, based on the chord, c, of the airfoil and free-stream velocity. The computational results reveal the dissipative nature, of SAS, associated with the turbulence modeling.
