F3D_15

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}
