ENDGAME - Laboratory Experiment 2022-11-28 Exp. 002 - Part 1 - 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). 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.采用高速相机与纹影阴影摄影（Schlieren shadow photography）技术开展预实验。本数据集采集了二维实验装置（2D setup）内多气泡上浮过程的图像：该装置由两块厚度为3mm的平行玻璃板组成，以橡胶密封圈分隔，内部填充蒸馏水，两块平行玻璃板的间隙为3mm。实验中通过直径4mm的吸管向该二维实验装置手动注入空气。所用高速相机的拍摄帧率为250 fps。纹影系统所使用的球面镜口径为75mm，焦距为750mm。
