Calculation of Heat Transfer to the Gun Barrel Wall

Abstract

Heat transfer to the barrel wall of a 155mm howitzer was calculated as part of an interior ballistics calculation with Gough's two phase flow code NOVA. The heat transfer coefficient between the core flow and the barrel wall was estimated by reference to a turbulent pipe flow correlation. The unsteady conduction in the wall was solved for the entire length of the chamber and tube.
