“…However, the maximum temperature is almost constant independent of the equivalence ratio. By the observation of jet atomization process under cold air flow condition, the maximum droplet mass flux somewhat decreased with increasing the equivalence ratio, that is, fuel flow rate 4 . Both the decrease of maximum fuel droplet mass flux and the increase of total fuel flow rate make the maximum temperature almost constant even with increasing the equivalence ratio.…”

“…Inamura et al [2] found that the liquid jet will bend into the cross-flow until the surface breaks into small droplets. Wu et al [3] observed by experiment that the liquid jet in the cross-flow eventually splits into a liquid belt and further small-sized droplets.…”

The experiment is conducted with a high-speed camera to investigate the breakup processes of liquid jets in uniform, shear-laden, and swirling cross-airflows. The liquid used in the test is water, the nozzle diameter is 2 mm, and the liquid-to-air momentum flux ratio q ranges from 5 to 3408.5. The results indicate that liquid jets break up to form small droplets in the uniform cross-airflow. There is an exponential relation between the broken position and q. In the shear-laden cross-airflow, the penetration depth of the jet is similar to that of the uniform case, both of which increase with the increase of q. When q and the mean Weber number are the same as the uniform case, the penetration depth of the jet increases by 25% when the velocity ratio of the upper and lower inlets is UR=5; the jet penetration depth decreases by 47.2% when the ratio of UR=0.2 and the jet breaks up quickly and the atomization effect will be better. In the swirling cross-airflow, the jet trajectory is similar to the uniform case and also satisfies the exponential property. When the swirl is weak (swirling number SN=0.49), the jet penetration depth increases compared to the uniform case; when the swirl is strong (SN=0.82), the cross-swirling airflow restrains the jet penetration depth.
