摘要：

Experimental skin friction results from constant free-stream velocity boundary layers are reported for a variety of constant and slowly varying injection and suction wall conditions. A description is given of the flow characteristics of these air experiments. The uniform injection results are in good agreement with the results of Kendall and the Stevenson, Rotta, and Kinney results from the Mickley-Davis data. For all turbulent flows examined, Cf 2 is found to be a a function of local Reθ and B. The friction factor ratio Cf Cfo|Reθ is found to be a function of B alone, and is given as an empirical function of B. Of seven theories examined, the theories of Rubesin and of Torii et al. are in best agreement with all of the results when considered on a local Ree and B basis. A simple calculation method of Cf 2 vs. Rex is suggested for slowly varying Vw(X). © 1969.
