Study on breakup of liquid ligaments in hypersonic cross flow using laser sheet imaging and infrared light extinction spectroscopy

This paper presents and discusses the results of tests of breakup phenomenon of liquid water into a hypersonic cross §ow from the surface of a 7 degree half-angle cone model at zero degree angle of incidence. The present work shows the dependence of the liquid phase characteristics on the cross-section area of the injection hole in a Mach 6 cross flow. The results are analyzed qualitatively by imaging, by Interferometric Laser Imaging for Droplet Sizing (ILIDS), and by InfraRed Light Extinction Spectroscopy (IR-LES). Conclusions are drawn concerning the droplet size distribution and the liquid §ow ¦eld characteristics.
