Relationship Between the Size of Mist Droplets and Ethanol Condensation Efficiency at Ultrasonic Atomization on Ethanol-Water Mixtures
High-frequency (2.4 MHz) ultrasonic irradiation to an ethanol-water mixture can induce the generation of ethanol-rich mist droplets at lower temperatures. Two groups of droplets in micrometer- and nanometer-sized were observed in the mist generated by the ultrasonic atomization. Nanosized droplets were considered to be ethanol-rich droplets which cause ethanol condensation. (C) 2009 American Institute of Chemical Engineers AIChE J, 56: 810-814, 2010
