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 Displacement thickness at X?

Displacement thickness at X calculator uses Displacement Thickness = Hydrodynamic Boundary Layer Thickness/8 to calculate the Displacement Thickness, The Displacement thickness at X formula is defined as the distance by which the external potential flow is displaced outwards due to the decrease in velocity in the boundary layer. Displacement Thickness is denoted by 𝛿^d symbol.
