On the Use of Accurate Ignition and Combustion Models in Internal Ballistics Gun Codes

摘要

The desire for increased performance from guns is driving the charge designer towards charges that pres-ent challenges to numerical modelling.There is a pressing need for accurate,validated ignition and combustion mod-els that can be used to predict the performance of advanced charges and ensure pressure waves are not developed or, if they are,then they can be managed.This paper describes efforts to model complex charge designs using a two-di-mensional axi-symmetric multi-phase flow internal ballistics model.
