Abstract

In this paper, we numerically solve the problem of detonation formation resulting from free flame propagation in an unconfined space. The mechanism of detonation formation that reduces to the local formation of shock waves during the development of the linear stage of unstable growth of disturbances formed on the surface of an expanding flame front is described. The basic criteria for creating conditions for the transition to detonation by the mechanism described are also formulated.

无限制空间内自由火焰传播时爆炸形成的机理

摘要

在本文中，我们用数值方法解决了在无限制空间内自由火焰传播引起的爆炸形成问题。描述了在膨胀火焰锋面表面上形成的扰动不稳定增长的线性阶段发展过程中，减少到局部形成冲击波的爆炸形成机理。还阐述了通过上述机制为爆轰过渡创造条件的基本标准。
