External_Flow_VerticalPlate_ND
Procedure External_Flow_VerticalPlate_ND(Re,Pr: Nusselt,C_f) returns the average Nusselt number and friction coefficient for flow past a infinitely long vertical plate of height W.
Inputs:
Re - Reynold's number [-], where
where r is the density of the fluid
m is the viscosity of the fluid
W is the height of the plate
u_f is the velocity of the flow
Pr - Prandtl number [-], where
where cp is the specific heat capacity of the fluid
k is the conductivity
Outputs:
Nusselt - average Nusselt number assuming a constant surface temperature[-]. The Nusselt number is defined:
where h_bar is the average heat transfer coefficient
C_D - average drag coefficient [-]. The friction coefficient is defined in terms of the drag force (F):
Notes
The correlation for Nusselt number is valid for 4E3<Re<1.5E4 as described in . The correlation for the drag coefficient is valid for Re>1E4
The Reynolds and Prandtl number are based on fluid properties evaluated at the film temperature, which is the average of the free stream and the surface temperature.
