F2D_15

Two infinitely long plates without a common edge angled with respect to one another

Function f2d_15 returns the view factor from an infinitely long flat plate to another infinitely long plate. The plates do not have to share a common edge. The included angle between them is a.

The calling protocol is:

F= f2d_15(x1, x2, y1, y2, alpha)

Inputs:
x1: distance from vertex to leading edge of plate 1 (ft or m)
x2: distance from vertex to trailing edge of plate 1 (ft or m)
y1: distance from vertex to leading edge of plate 2 (ft or m)
y2: distance from vertex to trailing edge of plate 2 (ft or m)
alpha: included angle between the plates (deg or rad)

Example:
$UnitSystem SI Mass J K Pa Degree
x1=1 [m]
x2=2 [m]
y1=1 [m]
y2=3 [m]
alpha=45 [deg]
F=f2d_15(x1, x2, y1, y2, alpha)

{~~Solution:~~
F=0.4915}
