Active control of jet breakup and droplet formation using temperature modulation

Different regimes of temperature modulated breakup were studied using a slender jet model. The instability is induced through capillary and Marangoni stresses can be used to control droplet formation in terms intact length resultant drop size distribution, which otherwise irregular due the inevitable presence background noise. When thermal modulation weak, surface tension gradient forces act only as trigger curvature-gradient soon take over grow exponentially downstream inertio-capillary growth. strong, not trigger, but remain significant till breakup.
