An experimental study has been performed for turbulent channel flow over an inclined backward-facing step. The inclination angle of the step is varied from 30° to 90°. The wall static pressure and local heat transfer coefficient are measured behind the inclined backward-facing step. The velocity profiles and turbulent quantities are measured by PIV. It was found that the pressure drop at the step was reduced and the heat transfer coefficient in the recirculating region was improved by leaning the backward-facing step. Enhancement of the heat transfer coefficient was related to the increase of turbulent energy, Reynolds shear stress and turbulent diffusions.
