Theoretical seminar | 08 September 2021

Acoustofluidics uses the mean force and torque produced by ultrasonic waves (also known as the acoustic radiation force and torque) with microfluidics technology to separate, enrich, pattern, and rotate cells, bacteria, and other microorganisms. This talk will discuss the physical principles of these mean acoustic fields stemming from the fluid dynamic conservation laws. Also, recent advances in the radiation force and torque description will be reviewed. Also, new trends of their modeling and applications in acoustofluidics will be outlined.
