Segregation of a liquid mixture by a radially oscillating bubble
Olivier Louisnard, Francisco Javier Gomez Romain Grossier
A theoretical formulation is proposed for forced mass transport by pressure gradients in a liquid binary mixture around a spherical bubble undergoing volume oscillations in a sound…
A simple model of ultrasound propagation in a cavitating liquid. Part II: Primary Bjerknes force and bubble structures
Olivier Louisnard
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 th…
A simple model of ultrasound propagation in a cavitating liquid. Part I: Theory, nonlinear attenuation and traveling wave generation
Olivier Louisnard
The bubbles involved in sonochemistry and other applications of cavitation oscillate inertially. A correct estimation of the wave attenuation in such bubbly media requires a realis…
Analytical expressions for primary Bjerknes force on inertial cavitation bubbles
Olivier Louisnard
The primary Bjerknes force is responsible for the quick translational motion of radially oscillating bubbles in a sound field. The problem is classical in the case of small-amplitu…
