Numerical Simulation of Current Artillery Charges Using the TDNOVA Code.

Abstract

The TDNOVA code provides a simulation of interior ballistic phenomena in guns. Interest is focussed on flamespreading through the charge and the development of pressure waves within the gun chamber. The code is designed to address the manner in which these phenomena are influenced by such details to design as the distribution of the igniter elements, the distribution of ullage, and the permeability, reactivity and strength of the containers used to package each of the charge increments. The model is based on a numerical solution of the governing equations of the macroscopic equations of two-phase heterogeneous flow with embedded discontinuities. The code is intended to be broadly applicable to gun propelling charges in general, however, medium caliber artillery charges have been of special interests. The principal objective of this report is to demonstrate the application of TDNOVA to a number of artillery charges of current interest. We discuss the representation of each of the charges by TDNOVA, the degree to which the simulation is affected by the numerical solution technique, and the sensitivity of the solutions to certain aspects of the packaging of the charge.
