This work examined the linear instability of a two-dimensional liquid film on an oscillating plane theoretically in the presence of a static electric field perpendicular to the plane. The liquid was considered to be viscous and perfectly conducting,

When combustion instability occurs, the pressure oscillation will result in periodic change, not only in the injector flow rate but also in the atomization characteristics of the injector. In this work, atomization characteristics of swirl injectors
