Plane formulation describes interaction of a shock with heavy gas cylinder and axisymmetrical models interaction with heavy gas bubble. Incident shock refraction and focusing processes are described including two different interaction patterns – external and internal. Three consecutive pressure peaks are found to occur at symmetry axis (or plane) inside and outside of the shocked inhomogeneity. A dependence of peak pressure values on initial gas density in the inhomogeneity is determined for three different shock Mach numbers. The highest pressure for plane and axisymmetric cases is shown to be reached in different interaction patterns. This study is performed in the Institute of Mechanics of Moscow State University using computational resources of MSU “Lomonosov” cluster with financial support of the Ministry of Education and Science of Russian Federation (contract No.14.G39.31.0001 from 13.02.2017).
