Breakup of a discontinuity in dispersed media at a various symmetry of motion

The evolution of waves is investigated numerically with use of the finite-difference schemes of the various order of accuracy derivated in homogeneous dispersible environment at the extension (compression) of final volume of enviroment, in an initial moment located at increased (reduced) pressure if there is a summetry of motion (flat, axial or central). It is shown, that depending on the entry conditions of disintegration in the field of current a various number of secondary shock waves appear.
