Abstract
The paper proposes a method for solving the problem of gas dynamics, implemented on the basis of a central difference scheme, the stability of which is achieved by performing a correction of the calcu-lated flows. It is shown that when solving the problem of discontinuity decay, the proposed method is stable, comparable in accuracy with the McCormack and Lax – Wendroff methods and surpasses them in performance.
