Outer surface of a small cylinder to the inner surface of a large cylinder when the small cylinder is completely outside of the large cylinder
Function f3d_23(l,d,y,r1,r2) returns the view factor between the outer surface of a small cylinder to the inner surface of a large cylinder when the small cylinder is completely outside of the large cylinder.
Inputs:
l = length of the smaller cylinder [m or ft]
d = distance between the ends of the cylinders [m or ft]
y = length of the larger cylinder [m or ft]
r1 = radius of the smaller cylinder [m or ft]
r2 = radius of the larger cylinder [m or ft]
Example:
$UnitSystem SI K Pa J rad
L=0.1 [m]
d=0.05 [m]
y=0.5 [m]
r1=0.1 [m]
r2=0.2 [m]
F = f3d_23(l,d,y,r1,r2)
{Solution:
F=0.1222}
