At the final stages of the lives of massive stars supernova explosion occurs. Before that process nuclear shell burning happens and strong turbulent convection arises in between iron core and silicon shell. Turbulence by amplifying flow in the post-shock region aid supernova explosion. In this work the physical mechanism behind this amplifi cation using a linear perturbation theory was investigated. Shock wave was modeled as one-dimensional planar discontinuity. Vorticity and entropy perturbations in the upstream flow considered as turbulence. Amplifi cation of
turbulent kinetic energy of ow crossing shock wave by a factor of 2 was obtained.
