Atomization characteristics and instabilities in the combustion of multi-component fuel droplets with high volatility differential
We delineate and examine the successive stages of ligament-mediated atomization of burning multi-component fuel droplets. Time-resolved high-speed imaging experiments are performed with fuel blendsExpand

Cu–Co–O nano-catalysts as a burn rate modifier for composite solid propellants
Abstract Nano-catalysts containing copper–cobalt oxides (Cu–Co–O) have been synthesized by the citric acid (CA) complexing method. Copper (II) nitrate and Cobalt (II) nitrate were employed inExpand

Puffing and Micro-Explosion Behavior in Combustion of Butanol/Jet A-1 and Acetone-Butanol-Ethanol (A-B-E)/Jet A-1 Fuel Droplets
ABSTRACT Butanol is mainly produced by acetone–butanol–ethanol (A-B-E) fermentation. The higher costs associated with the separation of butanol from the A-B-E mixture has prohibited the large-scaleExpand

Experimental investigations on nucleation, bubble growth, and micro-explosion characteristics during the combustion of ethanol/Jet A-1 fuel droplets
Abstract The combustion characteristics of ethanol/Jet A-1 fuel droplets having three different proportions of ethanol (10%, 30%, and 50% by vol.) are investigated in the present study. The largeExpand

Bubble dynamics and atomization mechanisms in burning multi-component droplets
We examine the complete sequence of events associated with the transition in the topology of a single droplet into multiple fragments of secondary droplets in the context of burning multi-componentExpand

Crown formation and atomization in burning multi-component fuel droplets
Abstract We report the observation of a crown-like sheet expansion and its subsequent atomization in burning multi-component fuel droplets. The droplets consisting of constituents with significantExpand

Phenomenology of disruptive breakup mechanism of a levitated evaporating emulsion droplet
Abstract Atomization of emulsion droplets is ubiquitous across a variety of application domains ranging from NextGen combustors to fabrication of biomedical implants. An understanding of theExpand

Universal dissolution dynamics of a confined sessile droplet
We experimentally investigate the dissolution of microscale sessile alcohol droplets in water under the influence of impermeable vertical confinement. The introduction of confinement suppresses theExpand
