Quantitative measurement of density by color schlieren based on axial symmetry field

Ye Jifei;Hong Yanji;State Key Laboratory of Laser Propulsion & Application,Academy of Equipment;  
The quantitative schlieren measure ment is new development of schlieren technology. A color filter was made for the substitute of the typical "Z" schlieren knife. The quantitative color schlieren method was advanced for measurement of the density of the axial symmetry field. A new approach was researched for the development of the quantitative schlieren technology based on the typical schlieren setting. The measurement theory and calibration method were introduced, and the typical setting was given as an applied example. Take the axial symmetry free jet as an object, the theory analysis and computer simulation results were contrasted with the experimental data. The results show the given method is suitable for the density quantitative measurement of axial symmetry field.
