    1980-1-1 · Kim and Marshall3 used an airblast nozzle of versatile design that provided two different configur- ations for the atomizing airflow. In one form, the atomizing air converged and expanded through an annulus around a liquid nozzle. In the alternative form, a secondary air nozzle was inserted axially in the liquid nozzle as shown in Fig. 4.
