The 53rd Fluid Dynamics Conference / the 39th Aerospace Numerical Simulation Symposium (June 30 - July 2, 2021. The Japan Society for Aeronautical and Space Sciences : Japan Aerospace Exploration Agency (JAXA), Online meeting)
In our laboratory, the characteristics of radiation behind air shock waves have been studied systematically by using a diaphragm-type shock tube. In previous studies, a simplified forced-rupture device with nichrome wire was introduced in the diaphragm-type shock tube. Shock waves were generated by the forced-rupture method. However, the rupture process of the forced-rupture method was different from the one of the natural rapture. In this study, the forced-rupture device was improved so that the diaphragms can be ruptured from one point in the center of the diaphragms. The shock waves were generated by using the improved forced-rupture device, and the pressure waveforms of the shock waves were obtained by using pressure sensors. The incident shock fronts were visualized by the Schlieren method.
