Utrasonic topic: "Ultrasonic Cavitation and its Applications"
When high-power ultrasound is coupled into liquid, acoustic cavitation occurs. Acoustic cavitation creates extreme conditions, including very high temperature and pressure differentials, turbulences, shear forces and liquid jets. These intense forces of ultrasonic cavitation are used for various applications such as homogenization, emulsification, dispersing & wet-milling, extraction, disintegration and sonochemical reactions.
