摘要

本文提出了一种求解气体动力学问题的方法，该方法是在中心差分格式的基础上实现的，其稳定性是通过对计算流量进行校正来实现的。结果表明，在解决不连续衰减问题时，所提出的方法是稳定的，精度与McCormack和Lax - Wendroff方法相当，性能优于它们。

ON THE USE OF THE CENTRAL DIFFERENCE SCHEME FOR SOLVING THE PROBLEM OF GAS DYNAMICS

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.
