Abstract
This article proposes a comprehensive framework for modeling the unsteady gas flows in muzzle devices (such as brakes, suppressors, and compensators), emphasizing three-dimensional (3D) computational fluid dynamics (CFD) combined with modern additive manufacturing (AM) techniques. Drawing on classical ballistic equations and recent research in muzzle-flow CFD, the paper highlights both traditional 1D2D analytical limitations and contemporary 3D numerical methods capable of capturing the full complexity of supersonic, turbulent flows with shock formation. Particular attention is given to Selective Microwave Melting (SMM), which broadens design possibilities for intricate multi-chamber geometries and internal baffles. An iterative modelprinttestrefine paradigm is outlined, facilitating rapid optimization of recoil-reduction efficiency, noise suppression, and material robustness. The presented synergy between 3D simulations and AM underscores a new era of advanced, reliable, and efficient muzzle devices for a range of armament applications.
