Nusselt number if heating starts from distance Xo from leading edge

Go Nusselt Number = 0.332*(Reynolds Number(x)^0.5)*(Prandtl Number^0.333)*(1-(Leading Edge Distance/Distance from Point to YY Axis)^0.75)^(-0.333)

Nusselt Number for Frame Module

Go Nusselt Number = ((0.74)*((Reynolds Number)^(0.2))*((Grashof Number*Prandtl Number)^(0.1))*((Prandtl Number)^(0.2)))

Nusselt number for liquid metals and for silicones

Go Nusselt Number = (0.3387*(Reynolds Number^0.5)*(Prandtl Number^0.333))/((1+(0.0468/Prandtl Number)^(0.67))^0.25)

Nusselt number for liquid metals or for silicones

Go Nusselt Number = (0.4637*(Reynolds Number^0.5)*(Prandtl Number^0.333))/((1+(0.0207/Prandtl Number)^(0.67))^0.25)

Nusselt Number using Blasius Similarity

Go Nusselt Number = ((0.664)*((Laminar Reynolds Number)^(0.5))*((Laminar Prandtl Number)^(1/3)))

Nusselt number for constant heat flux for external flow

Go Nusselt Number = 0.453*(Reynolds Number^0.5)*(Prandtl Number^0.333)

Nusselt number for constant wall temperature

Go Nusselt Number = 0.332*(Reynolds Number^0.5)*(Prandtl Number^0.333)

Nusselt number for liquid metals only

Go Nusselt Number = 0.565*(Reynolds Number*Prandtl Number)^0.5

Nusselt Number for Momentum Transport

Go Nusselt Number = (Friction Factor*Reynolds Number)/2

Average Nusselt number upto length L

Go Average Nusselt Number = 2*Nusselt Number(l)

Nusselt number at location L

Go Nusselt Number(l) = Average Nusselt Number/2

Average Nusselt number upto length L Formula

Average Nusselt Number = 2*Nusselt Number(l)
Nu_avgL = 2*Nu_L

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.
