Comparison of the mean skin friction with the heat transfer and the flow development in turbulent planar wall-attaching jet flows.

•Initial recovery length of the mean skin friction downstream of reattachment was proportional to Xr.•Longer recovery and initial decay of the mean skin friction depended on (x-Xr)/Hj.•Measures of the flow and heat transfer downstream of reattachment also depend on (x-Xr)/Hj.•Mean skin friction varied as Rej-0.2 below the attaching jet, in the reattachment region, and in the downstream wall jet.
