Three-Dimensional Numerical Fluid Flow Simulation of the Interior and Transitional Ballistics Process

Autor: Roman Wolbing, Barbara Baschung

Publikováno v: 31st International Symposium on Ballistics.

We report on the realization of a numerical tool to simulate the three-dimensional fluid flow associated with the interior ballistics problem of propellant based weapon systems. The model is based on a two-phase approach, in which the gaseous and the
