“…The penetration depth of the jet becomes lower due to more liquid mass loss derived from more droplet stripping. The result is consistent with the conclusion in subsonic flow in [43]. The penetration depth of the elliptical liquid jet (AR = 0:25) is 20% higher than the round liquid jet in Figure 9.…”

“…The spreading angle is defined in the upper right corner in Figure 10. Under the two-dimensional top view, the liquid drops from the center of the spray hole to the outermost edges of the left and right sides are straight lines, and the clamped angle is the spreading angle [43]. Figure 10 shows the spread angles at five different aspect ratios.…”

The study of elliptical liquid jets in supersonic flow in a Mach 2.0 is performed numerically. The primary breakup process of the elliptical liquid jet is simulated for a Weber number 223, liquid/gas flux momentum 4.0. The aspect ratios of elliptical geometries are set to be 0.25, 0.5, 1, 2, and 5. The results show a remarkable difference in liquid jet disintegration morphology at different aspect ratios. Under supersonic crossflow conditions, the elliptical liquid jet shows more breakup characteristics than the round liquid jet. As the aspect ratio grows, the penetration depth decreases. The elliptical liquid jet with AR=0.25 has the largest penetration depth in all cases. Moreover, the round jet has a maximum spreading angle of 50.2°. The changing trends of the column breakup length both x direction and y direction are similar. The elliptical jet at a lower aspect ratio has a shorter breakup length due to the narrower windward area. The liquid jet has a pair of larger horseshoe vortex structure and a wider wake region at a higher aspect ratio. Two pairs of reversal vortex pairs with obvious characteristics can be observed in all the simulations.
