Skin Friction Coefficient (Cf) is a dimensionless quantity that characterizes the frictional resistance between a fluid and a solid surface in a flow. It is used in fluid dynamics to quantify the effects of viscous forces on the flow over a surface. Turbulent flow is a type of fluid motion characterized by irregular and chaotic movement. The formula to calculate Skin friction Coefficient for turbulent as follows:
where:
- is the skin friction coefficient,
- is the Reynolds number based on the distance from the leading edge of the plate.
