Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a defined number of holes on its top and bottom lines, maintaining semi-captive air between itself and the gun. The case has been modeled and solved in COMSOL. Presented here are temperature fields as well as air flows immediately around the gun.
