F3D_33

Rectangle to perpendicular, centered disk

Function f3d_33(R, B, L) returns the view factor from a rectangle to a disk that is perpendicular to the rectangle. The plane containing the disk must include one edge of the rectangle and the disk must be touching the midpoint of that edge.

Inputs:
R = radius of the disk [m] or [ft]
L = length of the rectangle edge touched by the disk [m] or [ft]
B = length of the rectangle edge that is perpendicular to disk [m] or [ft]

Example:
$UnitSystem SI Mass J K Pa
R=1 [m]
B=1 [m]
L=1 [m]
F=f3d_33(R,B,L)

{Solution:
F=0.3116 }
