An Experimental and Theoretical Study on Ablative and Evaporative Cooling in the Interior Ballistics

Abstract

The report explores a better prediction of film cooling convective coefficient for a simplified model of the interior ballistics problem. The experiment includes design and modification of cooling projectiles, conversion and interpretation of experimental data. The theoretical study deals with the solution of gas dynamics and heat transfer in a unsteady compressible, two phase flow with nonisothermal wall. (Author-PL)
