Propagation of a shock-wave in a strongly inhomogeneous background

In this poster, we present the numerical solution of the evolution of a shock-wave which propagates through a large-scale rapidly changing inhomogeneous background. By using the publicly-available Pluto code, which is a modular Godunov-type code intended mainly for astrophysical applications, we investigate the radial evolution of a spherically expanding shock-wave for a variety of large-scale density profiles. Implications for shock-wave propagation in the Heliosphere and Solar corona will be discussed.
