High-Speed Photography of Particle Tracers Behind Non-Planar Shocks
A system has been developed for the photographic study of the flows produced by two—dimensional shocks generated in a shock tube. An array of particle tracers is injected into the gas being examined and the movement of the tracers, as well as the shock fronts, is recorded using a double pass schlieren system. A repetitively pulsed ruby laser, synchronized with a high speed 16mm framing camera, is used as a light source. Analysis of the photographic record yields the time and space variation of the physical properties of the observed flow field.
