Infinite Parallel Plates of Differing Widths with Common Centerline
Function F2D_10(a, b, c) returns the view factor between two infinitely long, directly opposed parallel plates that can have different widths.
Inputs:
a is the distance between the plates [m or ft]
b is the width of the plate 1 [m or ft]
c is the width of plate 2 [m or ft]
Example:
$UnitSystem SI K Pa J deg
a=1 [m]
b=1 [m]
C=2 [m]
F=F2D_10(a, b, c)
{Solution: F=0.6847}
This function is more general than F2D_1 in that it allows the plates to have different widths. It can also be applied if the widths are the same.
