Abstract:
Mechanism of global mixing in supernova ejecta is analyzed numerically. An axisymmetric system of hydrodynamic equations is solved using Eulerian scheme for various types of initial perturbations. We confirm the non-linear growth of perturbations near the H/He interface. We find that the reverse shock generated from the interaction between the blast shock and the H/He interface is essential for the growth of perturbations near the He/C + O interface. The perturbation near the He/C + O interface decays due to the interaction with the reverse shock. We conclude that a substantial amount of perturbations is required if the initial seed is originated from inside the He burning shell.
