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 Hydrodynamic boundary layer thickness at distance X from leading edge?
Hydrodynamic boundary layer thickness at distance X from leading edge calculator uses Hydrodynamic Boundary Layer Thickness = 5*Distance from Point to YY Axis*Reynolds Number(x)^(-0.5) to calculate the Hydrodynamic Boundary Layer Thickness, Hydrodynamic boundary layer thickness at distance X from leading edge formula is defined as a measure of the thickness of the boundary layer that forms over a flat plate when fluid flows over it, which is crucial in understanding the flow behavior and heat transfer characteristics. Hydrodynamic Boundary Layer Thickness is denoted by 𝛿hx symbol.
