Numerical simulation of shock dynamics in bubble systems
A numerical model of pressure and velocities field dynamics in the process of interaction of a plain shock wave with a "free" bubble system is suggested in the axisymmetric case. A comparison of the explicit and the splitting finite-difference schemes is made. Boundary conditions and the method of definition of error calculation of the exact value of maximum pressure amplitude in the focusing region are considered in details on the basis of estimation of the energy variation over the emanation wave.
