Abstract

The present paper is a study of laser Schlieren technique and its applications in kinds of flows from subsonic flow to high speed. Laser Schlieren technique has been investigated recently, which emitted 20mJ laser pulses at 5Hz. Owning to the benefits of light spot homogenization technique, laser Schlieren system was qualified to reveal the flow structures with high resolution and sensitivity. Benefited from these features, the laser Schlieren can be applied widely in fluid mechanism studies, including high speed flows, jets, butterfly flow field and so on.
