Abstract: The evolution of gas-dynamic perturbations in a heat-releasing medium was investigated in two-dimensional geometry under conditions of isentropic instability. Decomposition of the initial perturbation of “step” type, possessing transversal modulation (ripples) of front, into a sequence of flat autowave fronts predicted by a generalized nonlinear acoustic equation is shown. Evolution of localized perturbation results in decomposition into sequence of concentric autowaves. The front of two-dimensional structures is resistant to transversal modulation. A quasi-regular cellular structure is formed behind the fronts.
