Numerical research on adverse effect of muzzle flow formed by muzzle brake considering secondary combustion

Peng-Fei Li et al.

Summary: This study investigates the influence of a muzzle brake on muzzle hazard phenomena through simulation, analyzing the correlation of chemical reactions with muzzle flow field characteristics. The novel structure of muzzle flow caused by the muzzle brake is presented, and the secondary combustion phenomenon is explored using a chemical reaction kinetic model. Detailed analysis of blast waves interaction from the muzzle brake and mechanism of muzzle flash formation are provided, offering reference for future studies on suppressing muzzle flash.

Numerical Simulation and Analysis of Muzzle Flow During a Rarefaction Wave Gun Firing

Guannan Wang et al.

Summary: The rarefaction wave gun is able to significantly reduce recoil and barrel heat during launching while maintaining projectile velocity. This paper establishes mathematical models and numerical methods for muzzle flow, compares simulation results with experimental data, and investigates the differences in ballistic behaviors between the rarefaction wave gun and traditional gun. The rarefaction wave gun exhibits smaller main flow parameters and ballistic performances compared to the traditional gun due to the influence of the rarefaction wave.
