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 for liquid metals with constant heat flux?
Nusselt number for liquid metals with constant heat flux calculator uses Nusselt Number = 1.145*Peclet Number^0.5 to calculate the Nusselt Number, Nusselt number for liquid metals with constant heat flux formula is defined as a dimensionless quantity that characterizes convective heat transfer between a solid surface and a fluid, particularly in liquid metals with a constant heat flux, providing a crucial parameter in heat transfer analysis and thermal design. Nusselt Number is denoted by Nu symbol.
