A numerical model for muzzle blast flow fields
Abstract
A numerical model is formulated to describe the details of the flow field produced by the firing of a gun or mortar. Godunov's scheme with an alternating direction implicit (ADI) procedure is employed to discretize and integrate the time-dependent Euler equations. Sample results are given for an M-16 rifle and a 4.2-in. mortar. Numerical results agree reasonably well with the existing experimental data.
