Influence of hydrostatic pressure and gas content on continuous ultrasound emulsification.

摘要: Abstract Ultrasound is one means among others of producing emulsions mechanically. Droplet disruption in sonicated liquid–liquid systems considered to be controlled by cavitation. Both hydrostatic pressure and gas content the liquids influence probability intensity Continuous ultrasound emulsification experiments were carried out elucidate effect these parameters on result droplet disruption. Maximum energy density apparatus decreases with increasing pressure, probably due partial suppression cavitation which main mechanism power dissipation. At constant there no significant result, however. Corresponding results obtained for content. Gas saturation or degassing prior lead a shift maximum density. But, again, at clear size emulsion observed.
