Abstract. Convective heat transfer in the entrance region of a plane channel has been studied experimentally. Steady and pulsating air flow regimes have been considered. Heat transfer distributions over the channel wall have been obtained. Non-monotonous behavior of heat transfer coefficient has been revealed at some frequencies and amplitudes of forced flow pulsations. It was accompanied by heat transfer enhancement that was almost double for the local heat transfer coefficients. This may result from generation of vortices in the inlet duct in conditions of flow pulsations.
