ANALYSIS OF COMBUSTION PROCESSES IN A GUN INTERIOR BALLISTICS

This paper presents the numerical simulation of the gas-solid combusti on physics in a gun tube with a mobile projectile by means of a flux-c orrected transport nonlinear filtering scheme. The analysis is based o n a one-dimensional formulation of the two-phase flowfield with the sp ace-sharing interspersed continuum assumption. Apart from the Nobel-Ab el equation of state account the interphase drag and intergranular str ess between the solid-gas phase are taken into account. The computer c ode has been used effectively to study the pressure-wave propagation a nd flame dynamics in a gun barrel containing granular solid propellant s.
