F3D_30

Finite non-adjacent rectangles

Function F3D_30(x_1, x_2, y_1, y_2, eta_1, eta_2, z_1, z_2, theta) returns the view factor from area 1 to area 2 of two finite non-adjacent rectangles that are oriented at an angle theata to each other as shown .

Inputs:

x_1, x_2, y_1, y_2, eta_1, eta_2, z_1, y_2 are the lengths shown in the figure [m or ft.]

theta is the angle between the planes [deg or rad]

Example:

$unitSystem SI deg

x1=0[m]; x2=1[m]

y1=0[m]; y2=1[m]

eta_1=0[m]; eta_2=1 [m]

z_1=1[m]; z_2=2[m]

theta=45 [deg]

f=f3d_30(X1,x2,y1,y2,eta_1,eta_2,z_1,z_2,theta)

{Solution: F=0.07279}
