Disk to second coaxial disk within a cone
Function F3D_59(e,x,theta) returns the view factor between a circular disk and a second disk within a cone
Inputs:
e = distance from center of cone to disk 1 [m] or [ft]
x = distance from center of cone to disk 2 [m] or [ft]
theta = angle of cone [degree] or [radian]
Example:
$UnitSystem SI Mass J K Pa Radian
x=0.5 [m]
e=0.2 [m]
theta=30 [Degree]*convert(degree,rad)
F=F3D_59(e,x,theta)
{F = 0.1627}
