Abstract

In this paper, we consider the propagation and multiple reflection of a plane shock wave inside a channel with closed ends, one of which is protected by a screen of granular, easily destructible material. The wave propagated along the shock tube. When reflected from the end, it destroyed the protective shield and then was repeatedly reflected from both closed ends of the shock tube. The dependence of the pressure decrease at the front of the reflected shock wave on the protective layer thickness and the gap between the protective screen and the closed end of the shock tube is established.

颗粒材料筛对封闭空间内平面冲击波多次反射的影响

摘要

在本文中，我们考虑了平面冲击波在具有封闭端部的通道内的传播和多重反射，其中一个通道受到一列颗粒状，易于破坏的材料的保护。波沿激波管传播。当从末端反射时，它破坏了防护罩，然后又从减震管的两个封闭端反复反射。建立了反射冲击波前部的压力降低与保护层厚度以及保护屏与冲击管封闭端之间的间隙的依赖关系。
