| Abstract: | Experimental results on the mixing of non-aerated and aerated transverse liquid jet in supersonic cross flow (M = 1.5) are presented in this paper. The goal of this study is to investigate the effect of the gas/liquid mass ratio on the
penetration and atomization of an aerated liquid jet in high speed cross flow and to develop correlations for the penetration
heights. High speed imaging system was used in this study for the visualization of the injection of aerated liquid jet. The
results show the effect of jet/cross flow momentum flux ratio, the gas/liquid mass ratio and the Ohnesorge number on the penetration
of aerated liquid jet in supersonic cross-flow. New correlations of the spray penetration height for the non-aerated liquid
jet (GLR = 0) and the net gain in spray penetration height for the aerated liquid jet (GLR > 0) are presented. |
