Popis We study the hydrodynamics of collisions between expanding supernova ejecta of supernovae and asymmetric circumstellar material (CSM). For time-dependent hydrodynamic modeling we use our own grid-based Eulerian multidimensional unsplit hydrodynamic code that is highly efficient for calculation of shocks and physical flows with large discontinuities. We examine the behavior of density, pressure, velocity, and temperature in the interaction zone under various geometrical configurations and various initial densities of CSM. We expect that subsequent study of the SN light curves powered by such interaction thermal energy excess will lead to a better understanding of the mass and density distribution of the CSM.
