Consider a horizontal cylinder with diameter D and length L. The center of the cylinder is a distance a above the ground. A wall with length W and height H is located to the side of the cylinder at a distance L from the cylinder centre. The wall leans towards the cylinder with an angle θ from the vertical. The cylinder end is a distance S from the end of the wall. Determine the view factor between the cylinder surface and the wall as a function of the position around the circumference of the cylinder for the following case.

D = 1

L/D = 3

a/D = 1

H/D = 6

W/D = 10

θ= 0 and 30 degrees
