The inhomogeneity evolution problem is considered as a linear approximation in shock wave - contact breaking - shock wave configuration given the constant perturbation field of density before the front of one of the shock waves.
We use an approach in terms of entropy-vortex and sound waves collection. Shown here is the existence of three ranges of initial perturbation incidence angle on the shock front differing in medium behavior in the region behind the front. The maintenance conditions of shock perturbations are defined. Solutions are given for two wave vectors of initial perturbations.Keywords: hydrodynamic inhomogeneity, entropy-vortex waves, sound waves, shock front perturbation.
