ENDGAME - Laboratory Experiment 2022-11-29 Exp. 005 - Part 3 - High Speed Camera data

Preliminary test with high speed camera and Schlieren shadow photography. Images of the injection of air in a 2D setup obtained using 2 parallel glass sheets (3 mm thickness) separated by rubber seals and filled with a viscous fluid. The viscous fluid is obtained mixing distilled water with a hair gel (2/3 distilled water, 1/3 hair gel). The gap between the two parallel sheets is 3 mm. Air was injected into the 2D setup through a capillary tube (~2 mm diam) with constant flow rate (~13x10^-3l/s). Frame rate of the high speed camera is 250 fps. The spherical mirror has been covered in order to acquire only optical images and compare them with the corresponding Schlieren shadow photography images (ENDGAME_LabExp_HighSpeedCamera_20221129_003_XXX and ENDGAME_LabExp_HighSpeedCamera_20221129_004_XXX).采用高速相机（high speed camera）与纹影阴影摄影（Schlieren shadow photography）技术开展预实验。本实验针对二维实验装置开展空气注入成像，该装置由两片厚度为3mm的平行玻璃板构成，玻璃板间隙通过橡胶密封件固定，内部填充粘性流体。该粘性流体通过将蒸馏水与发胶按2/3蒸馏水、1/3发胶的比例混合配制而成。两片平行玻璃板之间的间隙为3mm。通过直径约2mm的毛细管（capillary tube）以恒定流量（约13×10^-3升/秒）向该二维装置中注入空气。高速相机的帧率为250 fps。为仅获取光学图像并将其与对应的纹影阴影摄影图像进行对比，对球面镜进行了遮挡处理，相关实验数据集编号为ENDGAME_LabExp_HighSpeedCamera_20221129_003_XXX与ENDGAME_LabExp_HighSpeedCamera_20221129_004_XXX。
