The basic processes in the projectile impact of slurry explosives containing gas bubbles are investigated numerically using a two‐dimensional unsteady state model. The partial differential equations derived from the laws of conservation of mass and momentum, together with the equation of state proposed by Tait are solved by means of a finite difference TENSOR computer code. The model describes the continuous time dependence of the pressure, velocity and displacement in the slurry explosive under dynamic loading.
