Abstract

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. © 2009 American Institute of Chemical Engineers AIChE J, 2010
