Preliminary 2D Shock-tube experiments in combination with high speed Schlieren shadow photography. 

We developed a 2D shock-tube setup using 2 glass sheets (1 cm width) separated by 2 lateral bars (gap between glass sheets 1.3 cm). We injected compressed air into the 2D setup at different overpressures (up to 8 bar). The high-pressure reservoir is connected with the 2D apparatus through a diaphragm pulse valve which allows a fast release of pressurized gas into the system. Images were collected at a frame rate of 30000 fps. The field of view of the images show the jet flow dynamics in the upper part of the 2 glass sheets and in the atmosphere.
