ENDGAME - Laboratory Experiment 2022-11-30 Exp. 002 - 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 (4/5 distilled water, 1/5 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 (~10-2 l/s). 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.
