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 and silicones with higher Reynolds number value?
Nusselt number for liquid metals and silicones with higher Reynolds number value calculator uses Nusselt Number = 0.3+((0.62*(Reynolds Number^0.5)*(Prandtl Number^0.333))/(1+((0.4/Prandtl Number)^0.67))^0.25)*(1+(Reynolds Number Dia/282000)^0.5) to calculate the Nusselt Number, Nusselt number for liquid metals and silicones with higher Reynolds number value formula is defined as a dimensionless quantity that characterizes convective heat transfer between a fluid and a solid surface, particularly in flow over cylinders, where the Reynolds number is high. Nusselt Number is denoted by Nu symbol.
How to calculate Nusselt number for liquid metals and silicones with higher Reynolds number value using this online calculator? To use this online calculator for Nusselt number for liquid metals and silicones with higher Reynolds number value, enter Reynolds Number (Re), Prandtl Number (Pr) & Reynolds Number Dia (ReD) and hit the calculate button. Here is how the Nusselt number for liquid metals and silicones with higher Reynolds number value calculation can be explained with given input values -> 1.384946 = 0.3+((0.62*(5^0.5)*(0.7^0.333))/(1+((0.4/0.7)^0.67))^0.25)*(1+(5.5/282000)^0.5).
