What is external flow
In fluid mechanics, external flow is such a flow that boundary layers develop freely, without constraints imposed by adjacent surfaces. Accordingly, there will always exist a region of the flow outside the boundary layer in which velocity, temperature, and/or concentration gradients are negligible. It can be defined as the flow of a fluid around a body that is completely submerged in it.
An example includes fluid motion over a flat plate (inclined or parallel to the free stream velocity) and flow over curved surfaces such as a sphere, cylinder, airfoil, or turbine blade, air flowing around an airplane and water flowing around the submarines.
How to Calculate Local Friction Coefficient given Reynolds Number?
Local Friction Coefficient given Reynolds Number calculator uses Local Friction Coefficient = 0.664*Reynolds Number(x)^(-0.5) to calculate the Local Friction Coefficient, Local Friction Coefficient given Reynolds Number formula is defined as a dimensionless quantity that characterizes the frictional force exerted by a fluid on a flat plate, providing a measure of the resistance to fluid flow over a flat surface, which is essential in understanding various engineering and physical phenomena. Local Friction Coefficient is denoted by Cfx symbol.
