ENDGAME - Laboratory Experiment 2022-12-01 Exp. 001 - Part 3 - High Speed Camera data

Preliminary test with high speed camera and Schlieren shadow photography. Images of the injection of air bubbles in a 2D setup obtained using 2 parallel Plexiglas sheets (10 mm thickness) separated by rubber seals and filled with a distilled water. The gap between the two parallel sheets is 3 mm. Air was injected manually into the 2D setup through a capillary tube (~2 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.本预实验采用高速相机与纹影阴影摄影法（Schlieren shadow photography）开展。实验获取了二维实验装置内空气气泡注入过程的图像：该装置由两块厚度为10mm的平行有机玻璃（Plexiglas）板搭建，板间以橡胶密封条密封并填充蒸馏水，两块平行板的间距为3mm。空气通过直径约2mm的毛细管（capillary tube）被手动注入该二维实验装置。高速相机的拍摄帧率为250 fps。本次纹影系统所使用的球面镜宽度为75mm，焦距为750mm。
