Abstract

A method was developed in order to predict the time dependent temperature distributions in a canon barrel during firing. The main goal of the work is to develop and validify a model which delivers accurate results with minimal effort to be used for parametric studies. The model is made up of three main components: namely, a one-dimensional, mviscid, non-steady, reacting real gas core How; a quasi-steady, axisymmet- ric turbulent boundary layer; and the non-steady heat transfer in an axi- symmetric tubular structure. The mviscid core flow is assumed to be independent of the growth of the boundary layer and the heat transfer to the walls. Distinct to the model is the intimate c
