ENDGAME - Laboratory Experiment 2023-11-06 Exp. 003 - High Speed Camera data
<p>Preliminary 2D Shock-tube experiments in combination with high speed Schlieren shadow photography. </p> <p>We developed a 2D shock-tube setup using 2 plexiglass sheets (30 cm x 50 cm x 1 cm) separated by 2 lateral bars (gap between plexiglass sheets 1.2 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. The 2D setup was either empty (i.e. with air at ambient conditions) or filled with a given amount of fluids (water or viscous fluid) or small particles. Images were collected at a frame rate of 50000 fps. The field of view of the images show the jet flow dynamics within the 2 plexiglass sheets (vent is outside the field of view). </p> <p>By using Schlieren shadow photography we can see the presence of some textures in the images, which are likely to be generated by the plexiglass sheets. </p>
