Finite adjacent plates
Function F3D_28(a, b, c, theta) returns the view factor from area 1 to area 2 of two finite rectangles of the same length, having one common edge with an angle theta between the plates.
Inputs:
a = height of area 1 [m or ft]
b = height of area 2 [m or ft]
c = length of common edge as shown in the figure [m or ft]
theta = angle between the places [deg or rad]
Note: The input values have to be greater than 0!
Note: Use F3D-2 if the angle between the plates is 90°.
Example:
$UnitSystem SI K Pa J deg
a=1 [m]
b=1 [m]
c=1 [m]
theta=45 [deg]
F=F3D_28(a, b, c, theta)
{Solution: F=0.4833 }
