skin friction

[′skin ‚frik·shən]
(fluid mechanics)
A type of friction force which exists at the surface of a solid body immersed in a much larger volume of fluid which is in motion relative to the body.

skin friction

The frictional resistance developed between soil and a structure or between soil and a pile being driven in it.

There are three types of parasitic drag: form drag (from blunt, non-lift producing surfaces), interference drag (from mixing air flows) and skin friction.
Substituting (7), (8), and (15) into (16), we receive the terms for the skin friction and local Nusselt and Sherwood numbers as follows:

According to Kelley and Lutenegger (2004), the skin friction obtained by torque measurement has a good correlation with the Cone Penetration Test (CPT) sleeve measurements, and the N value.
The wall skin friction loss usually increases as the variation of blade angle increases because the increase in the blade surface area.
In studies that reveal what athletes perceived to be important 'must-have' effects in their sportswear and first layer garments, skin friction and comfort came out tops amongst other effects such as moisture management, odor control and thermal control.
Although the skin friction acting on the turbulent ball is higher than that of a laminar one, the form or pressure drag resulting from the wake represents the bigger contribution to the overall drag.
The non-dimensional form of the skin friction at the porous plate is given by
