Plane element dA_1 to a cylinder



Function fDiff_18(R, L, H) returns the view factor from a differential area to a cylinder when the area is facing the cylinder and located at its endpoint.

The calling protocol is:

F= FDiff_18(R, L, H)

Inputs:
R radius of the cylinder [m or ft]
L length of the cylinder [m or ft]
H distance between centerline of cylinder and area [m or ft]

Hamilton, D.C. and Morgan, W.R., 1952, "Radiant-interchange configuration factors,"NASA TN 2836. 

Example: 
$UnitSystem SI
R=1 [m]
H=1.5 [m]
L=2 [m]
F=fdiff_18(R,L,H)

{Solution:
F=0.3297}
