The skin friction line is a concept often used in fluid dynamics, particularly in the study of boundary layers and turbulent flows. It represents the distribution of shear stress due to viscosity along a surface in contact with a fluid. In the context of flow over a surface, such as an airfoil or a flat plate, the skin friction line indicates the point where skin friction (the frictional resistance due to the viscosity of the fluid) is acting on the surface of the object.
