Abstract�� A two-equation turbulence model with additional term for Coriolis and buoyancy was used to predict turbulent flow and heat transfer in a rotating smooth serpentine passage. Using pressurized air as the coolant, operating conditions were selected to closely match the real turbine operating parameters. The results indicated that increasing the rotation number tend to increase averaged ��Nu�� value and the decrease ��Eu�� value, though there are variations in heat transfer on different sides.
Keywords�� gas turbines   cooling blades   convective heat transfer   spining
