摘要：

The problem of transpired turbulent boundary layers subject to external pressure gradients has been analyzed using the similarity analysis of the equations of motion. Two main results were found. Firstly, the mean deficit profiles in zero pressure gradient (ZPG) or adverse pressure gradient (APG) boundary layer collapse with the free stream velocity, but to different curves depending on the blowing parameter and external pressure gradient. Secondly, the dependence on the blowing parameter and pressure gradient is completely removed from the outer flow when the mean deficit profiles are normalized by the Zagarola and Smits scaling.
