Shock tubes
Web1 Feb 2024 · A compression-driven shock tube was devised in 1899 by a French physicist [1]. The pipe diameter was 0.6 to 2 m, the tube length was 3 to 15 m, and it created 7 to 200 MPa shock waves [2]. Shock waves were used to research chemical transformations, high temperature and self-ignition on gasses and fuels, and Nano particle dynamics. Web23 hours ago · Pressure is mounting on Sen.
