Prediction of turbulent flow and heat transfer within rotating smooth U-shaped passage

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 U-shaped passage. Using pressurized air as the coolant, operating conditions were selected to closely match the real turbine operating parameters. The results indicate that increasing the rotation number tends to increase averaged Nu value and decrease Eu value, though there are variations in heat transfer on different sides.
