A universal friction law for turbulent boundary layers on a flat plate with suction is established. Experimental skin‐friction distributions obtained for various suction factors and Reynolds numbers are described in similarity variables by a single universal curve. The law is valid for the entire range of suction velocities from zero one till the limiting values corresponding to asymptotic‐suction boundary layers. The analysis is not based on any particular turbulence model. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
