Influence of the shape of the orifice on the local heat transfer distribution between smooth flat surface and impinging incompressible air jet

•Heat transfer of a flat surface impinged by different shaped jets is studied.•Effect of shape of the orifice and jet to plate distance is studied.•Local heat transfer distribution is obtained by infrared thermal imaging technique.•Axis switching is observed for all the shapes.•Local heat transfer d...
