ENDGAME - Laboratory Experiment 2024-03-19 Exp. 006 - High Speed Camera data

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 within the 2 glass sheets (vent is outside the field of view).

本研究开展初步二维激波管（2D shock-tube）实验，结合高速纹影阴影摄影（Schlieren Shadow Photography）技术。
我们搭建了一套二维激波管实验装置：采用两块宽度为1厘米的玻璃板，通过两根侧向支撑杆分隔，玻璃板间距为1.3厘米。向该装置内注入不同超压（最高可达8巴）的压缩空气。高压储气罐通过膜片式脉冲阀与该二维实验装置相连，可实现加压气体的快速释放入系统。图像采集帧率为30000帧每秒（fps）。
图像视场范围覆盖两块玻璃板内部的射流流场动力学特性，排气口位于视场之外。
