Finite adjacent plates
Function f3d_29(a_1, a_2,b_1,b_2,c, theta) returns the view factor from area 1 to area 2 of two finite rectangles that are oriented at an angle theata to each other as shown .
Inputs:
a_1, a_2, b_1, b_2 and c are the lengths shown in the figure [m or ft.]
theta is the angle between the planes [deg or rad]
Note: The input values must all be greater than 0!
Example:
$UnitSystem SI K Pa J deg
a_1=0.1 [m]
a_2=0.5 [m]
b_1=0.2 [m]
b_2=0.3 [m]
c=0.5 [m]
F=f3d_29(a_1, a_2,b_1,b_2,c, 45)
{Solution:
F=0.2276}
Note that this function returns the same result as f3d_11 if the angle between the planes is 90°
This function uses f3d_28 and view factor relationships.
