A simple model of ultrasound propagation in a cavitating liquid. Part II: Primary Bjerknes force and bubble structures [PDF]
, 2012 In a companion paper, a reduced model for propagation of acoustic waves in a cloud of inertial cavitation bubbles was proposed. The wave attenuation was calculated directly from the energy dissipated by a single bubble, the latter being estimated ...

The nonlinear dynamics of flexural ultrasonic transducers [PDF]
Proceedings of Meetings on Acoustics, 2019 Dynamic nonlinearity can manifest as changes in characteristic properties of a vibrating system in response to variations in excitation. This study investigates the nonlinearity in the vibration response of the flexural ultrasonic transducer. This device is typically employed for industrial measurement, but little is known about the influence of ...

Ultrasonic Wave Mixing for Nonlinear Ultrasonics in a Microfluidic Capillary [PDF]
2019 IEEE International Ultrasonics Symposium (IUS), 2019 In this study we show that nonlinear ultrasonics, based on nonlinear wave mixing, can enable the measurement of the interactions between acoustic waves and a microliter liquid sample in a glass capillary microchannel. This has the potential to deliver new techniques with a high sensitivity to acoustic material properties.
