Finite plane to finite cylinder
Function F3D_15(l, n, z, d) returns the view factor from a finite plane to a finite cylinder. The plane and cylinder are the same height and plane edge nearest the cylinder is defined by its normal passing through the axis of the cylinder.
Inputs:
l = width of the plane [m or ft]
n = distance between the cylindrical axis and the plane [m or ft]
z = height of the plane [m or ft]
d= diametr of the cylinder[m or ft]
Example:
$UnitSystem SI K Pa J rad
l=0.5 [m]
n=0.2 [m]
z=0.5 [m]
d=0.25 [m]
F=F3D_15(l, n, z, d)
{Solution: F=0.2435}
