On satellite drop formation in liquid jet atomization
Abstract
Satellite drops found in experiments at low speed jet breakup are recoginzed as a nonlinear phenomenon. Rigorous mathematical arguments are presented to analyze and explain several fundamental equations, such as: why satellite drops are formed in circular jet and not in planar jets, whether saltellite drop formation depends on the amplitude of initial disturbance, and the effect of disturbance wavelength on the size of the drop. The analysis reveals that the satellite drop is a result of the development of the high harmonics, which is due to the nonlinearity of the jets cross-section. Analytical solutions of the surface wave growth process are derived to validate the direct numerical simulations of the liquid jet breakup.
