In order to obtain the jet impingement heat transfer characteristics of aero-engine inlet cone, a series of impingement heat transfer experiments were carried out in a curved surface channel using Transient Liquid Crystal (TLC) temperature measurement technique. The effects of jet Reynolds number (Rej), cross flow Reynolds number (Rec), dimensionless hole space (P/d) and impingement distance (H/d) on Nusselt number (Nu) of the full surface were investigated, which can provide important reference for the hot air anti-icing system of aero-engine.
