Abstract

An analytical method for determining the amplitude and velocity of an autowave pulse emerging in isentropically unstable heat-releasing media is presented. The method is suitable for any values of acoustic dispersion and growth rate and requires the knowledge of heat-loss function only without the need for a numerical solution of a complete system of gas-dynamic equations.

具有加热/冷却不平衡和任意热分散的介质中的自动波脉冲

摘要

提出了一种确定在等熵不稳定的热释放介质中出现的自动波脉冲的幅度和速度的分析方法。该方法适用于任何声扩散和增长率值，并且仅需要热损失函数的知识，而无需对完整的气体动力学方程组进行数值求解。
