ENDGAME - Laboratory Experiment 2022-11-29 Exp. 002 - Part 2 - High Speed Camera data

Preliminary test with high speed camera and Schlieren shadow photography. Images of the rise of two coalescing 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.
