Parallel cylinders of finite and equal lengths
Function F3D_35(r_1, r_2, L, s) returns the view factor between two aligned cylinders of finite but equal length.
Inputs:
r_1 and r_2 = radii of the cylinders [m] or [ft]
L = length of the cylinders [m] or [ft]
s = distance between the cylinders [m] or [ft]
Example:
$UnitSystem SI Pa J K m
r_1=0.1 [m]
r_2=0.2 [m]
L=0.2 [m]
s=0.1 [m]
F=F3D_35(r_1,r_2,L,s)
{Solution: F=0.1028 }
