Shock tube physics
Web1 Jan 1981 · A shoek tube is basically a pipe or duct which is divided into two sections separated by a diaphragm which permits differential pressurization. When the diaphragm is suddenly removed, a shock wave, that is a near-discontinuity in pressure propagates into the low pressure section while an expansion wave travels into the high pressure chamber. WebFigure 1: A schematic diagram of a conventional shock tube The analysis of the shock tube played an important part in understanding the details of the propagating shock formed within the tube and the necessary conditions required to generate a shockwave. The analysis was carried commercial FEM package COMSOL Multi-physics. The shock tube is ...

Web22 Jan 2024 · A shock absorber or damper is a mechanical or hydraulic device used to absorb and damp shock impulses. This is done by converting the kinetic energy of the shock into another form of energy (typically heat), which is then dissipated. Most shock absorbers are some sort of dashpot (a damper that resists motion by viscous friction).
