Analytical Studies of Transient Film-Cooling Effectiveness

Abstract

An analytical model has been developed for two problems of gun barrel cooling: a. film cooling with wear reducing additives and b. liquid film cooling. The governing equations were derived from an integral method and the solutions of the film-cooling effectiveness were obtained by application of the characteristic method. The results found earlier are: (a) with the additives, the effectiveness is very significant in a region where the erosion is most series and (b) with liquid cooling, the effectiveness is in general high. It is, however, smaller in that region.
