Paper Abstract

The quantitative rainbow schlieren technique was applied to measure density grads and density in flow flied widely. The experiment took the axis-symmetry unexpended supersonic free jet as a object, used the typical "Z" schlieren system and replaced the edge with rainbow filter. Different rainbow filter was designed to study the sensitivity and validity in the quantitative measurement. While schlieren measurements were compared with numerical value using FLUENT. Good agreement between the measurement and numerical value was achieved on the unexpended-supersonic jet.
