ENDGAME - Laboratory Experiment 2022-11-29 Exp. 001 - Part 2 - High Speed Camera data

Preliminary test with high speed camera and Schlieren shadow photography. Images of the rise of multiple air bubbles in a 2D setup obtained using 2 parallel glass sheets (3 mm thickness) separated by rubber seals and filled with distilled water. The gap between the two parallel sheets is 3 mm. Air was injected manually into the 2D setup through a straw (4 mm diam) at high speed. Frame rate of the high speed camera is 250 fps. The spherical mirror used for the Schlieren setup was 75 mm wide with a 750 mm focal length.本研究采用高速相机与纹影阴影摄影（Schlieren shadow photography）技术开展预实验。实验采集的影像为多气泡在二维实验装置内的上浮过程，该装置由两块厚度为3mm的平行玻璃板组装而成，辅以橡胶密封件进行密封，内部填充有蒸馏水。两块平行玻璃板之间的间隙为3mm。通过直径为4mm的吸管以高速向该二维实验装置内手动注入空气。高速相机的帧率为250 fps。本次纹影装置所使用的球面镜口径为75mm，焦距为750mm。
