Abstract

Disintegration mechanism through a liquid-phase feedback loop is explored for a circular liquid jet issued into an otherwise quiescent gas. An asymptotic analysis of capillary waves radiating from the liquid jet tip is used to derive analytical expression for the feed back loop for the regular axisymmetric liquid jet disintegration occurring at a large distance from the nozzle exit for various Weber numbers. The calculation results predict the breakup characteristics which are consistent with the experimental observations. The role of turbulence contained in the issued jet and the change in atomization feature at large Weber numbers are also discussed briefly.
