F3D_34

Interiors of aligned rectangular enclosures

Function f3d_34(x_1, x_2, s, b, d) returns the view factor from the internal surface of two aligned rectangular enclosures.

Inputs:
x_1 = width of enclosure 1 [m] or [ft]
x_2 = width of enclosure 2 [m] or [ft]
s = gap between enclosures [m] or [ft]
b and d = dimensions of the enclosure in directions perpendicular to the aligning axis

Example:
$UnitSystem SI Mass J K Pa
x_1=1 [m]
x_2=1 [m]
s=0.2 [m]
b=1 [m]
d=2 [m]
F=f3d_34(x_1,x_2,s,b,d)

{Solution:
F=0.1294 }
