Abstract
The effect of the chamber geometry of tube weapons on the performance and on the interior ballistic two-phase flow is investigated by applying the 2-D model AMI. The axisymmetric formulation in AMI has been modified such that arbitrary chamber shapes can be considered without any simplifying assumptions. The numerical results for large caliber systems show interesting flow patterns caused by the axial changes in cross-section, e.g., by the transition cone. The numerical procedure is explained. Computational results emphasize the differences between a constant diameter chamber-bore configuration and a configuration with chambrage, i.e. with non-constant diameter.
