Aerodynamic breakup of liquid jets - A review
Abstract
There are many applications for which it is important to understand the breakup of a liquid glob or jet into droplets (e.g., propulsion, control, and cooling of system components). The aerodynamic breakup of liquids is a complex process and is affected by the geometry, flow conditions and the liquid properties. This paper summarizes the results of several studies on the subject and discusses features of the phenomena which appear to be possible mechanisms in the liquid breakup process. The acceleration waves are the most likely mechanism responsible for the liquid breakup with secondary influence from the liquid properties, surface tension and viscosity. Correlations are presented for predicting the stability of liquid drops and breakup conditions. The results of this analysis will help toward better understanding of the role of aerodynamic forces in the breakup of liquids.
