Fig. 7 Ultra-high-speed visualization of water spray in the FB injector near field for ALR = 2 at
spatial resolution of 7.16 µ m/pixel and exposure time of 1 µ s
Figure 7 depicts an air bubble at the injector exit that expands, explodes, and
shatters the surrounding liquid into droplets, visually illustrating the liquid breakup
by FB atomization. Surprisingly,
the majority of the liquid has already been
atomized into
fine droplets at the injector exit indicating that the liquid breakup by
