ENG ME 721: Acoustic Bubble Dynamics
Undergraduate Prerequisites: ENG ME 520 and ENG ME 542; or equivalent
Bubbles and acoustic cavitation play an important role in many aspects of application of sonic and ultrasonic energy in fluids and biological tissue. This course will introduce the study of bubble phenomena in sound fields. The fundamental physical acoustics of bubbles and the fundamental physics which can be illustrated by the study of bubble dynamics will be stressed.
