F3D_16

Sphere to disk

Function f3d_16(r, h) returns the view factor between a sphere (surface 1) located on a line that is normal to the center of a disk (surface 2).

Inputs:
r = radius of the disk [m or ft]
h = distance between the center of the sphere and the center of the disk [m or ft]

Example:
$UnitSystem SI K Pa J rad
r=1 [m]
h=0.5 [m]
F=f3d_16(r, h)

{Solution: F=0.2764}
