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 Nusselt number at distance x from leading edge?
Nusselt number at distance x from leading edge calculator uses Nusselt Number(x) = 0.0296*(Reynolds Number(x)^0.8)*(Prandtl Number^0.33) to calculate the Nusselt Number(x), Nusselt number at distance x from leading edge formula is defined as a dimensionless value that characterizes the convective heat transfer between a fluid and a flat plate at a specific location, providing a measure of the heat transfer rate in the boundary layer. Nusselt Number(x) is denoted by Nux symbol.
How to calculate Nusselt number at distance x from leading edge using this online calculator? To use this online calculator for Nusselt number at distance x from leading edge, enter Reynolds Number(x) (Rex) & Prandtl Number (Pr) and hit the calculate button.
