Abstract

Adverse pressure gradient (APG) turbulent boundary layers (TBLs) are found when the flow takes place over the diverging part of curved surfaces, like flow over the leeward side of an aerofoil section. This paper reports on a study of the various factors contributing to the skin friction coefficient in such flows. Specifically, it deals with the contributions to the wall shear stress from Reynolds stress, viscous effects and pressure gradient in an incompressible turbulent boundary layer flow. The skin friction coefficient is expressed in terms of the decomposition suggested by Renard & Deck [6] for boundary layer flows.
