Separation of two fractions of immiscible liquids by ultrasound in microgravity

Ultrasonic separation of two immiscible liquids under microgravity conditions has been demonstrated on example of liquid mixtures of FC-70 or FC-72 with silicone oils of 1.5 or 1.0 cSt viscosities, respectively. A 3-MHz focused ultrasound beam was utilized to form an emulsion from these liquid combi...

Zusammenfassung:Ultrasonic separation of two immiscible liquids under microgravity conditions has been demonstrated on example of liquid mixtures of FC-70 or FC-72 with silicone oils of 1.5 or 1.0 cSt viscosities, respectively. A 3-MHz focused ultrasound beam was utilized to form an emulsion from these liquid combinations, and a plane wave of the same frequency served to separate (demix) fluids. Droplet deformation under pulsed ultrasound in microgravity conditions is reported, and the observed singular behavior is discussed.
