Radiation Shielding of a Spherical Body

This simulation shows how a radiation shield affects radiative heat transfer to a ball. The ball in the center is the object that is shielded; you can remove the shield by unchecking the “shield control” checkbox. The enclosure around the shield and ball is assumed to be a black body at a temperature of 600 K. The radiation shield diameter is 0.2 m larger than the ball diameter, and the shield is assumed thin enough that conductive heat transfer can be ignored. Three views are possible: a 3-D physical representation, a radiation network, and a plot of the radiative heat transfer from the enclosure to the ball as a function of the emissivity of the shield.
