Abstract:

Large eddy simulations are performed to study the flow physics and heat transfer for the film-cooling of gas turbine blade surface. The coolant jet issues out from a cylindrical delivery tube into the mainflow at an inclination angle of 35 degrees. The Reynolds number based on the jet velocity and the diameter of the delivery tube is approximately 11100. The jet to mainflow velocity ratio is 0.5. Heat transfer calculations are also performed simultaneously to study the mixing of the passive scalar with the mainflow, evaluate film-cooling effectiveness and heat transfer predictions on the blade surface. The parameters in the simulation correspond to the experiments performed at UTRC Lavrich and Chiappetta, 1990.
