Research Abstract |
A rainbow schlieren system has been employed to determine the density fields in the underexpanded sonic jet from a cylindrical nozzle. As a result, the jet structure can be clearly observed by schlieren pictures with horizontal and vertical rainbow filters. Density profiles at any jet cross-section can be efficiently inferred from the Abel inversion of the schlieren images. Also, an analytical model to predict the flow properties through the cylindrical nozzle is proposed and compared with the present experimental results. Furthermore, conventional and improved nozzles for peeling leeks are used for qualitative and quantitative comparison of jets from their nozzles by the rainbow schlieren deflectometry. It is found that the jet from the improved nozzle has a high removing potential for peeling leeks in comparison with the conventional one.
