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（high speed camera）与纹影阴影摄影（Schlieren shadow photography）开展初步试验。本次实验采集了二维装置内多组气泡上升过程的图像，该二维装置由两块以橡胶密封件分隔的平行玻璃板（厚度3mm）搭建，内部填充蒸馏水；两块平行玻璃板的间隙为3mm。实验人员通过直径4mm的吸管向该二维装置内手动注入空气。高速相机的帧率为250 fps。纹影装置所使用的球面镜口径为75mm，焦距为750mm。
