Rectified diffusion and single‐bubble sonoluminescence

Earthquakes, volcanoes, and rectified diffusion

Rectified diffusion is a mechanism by which a strain wave can rapidly pump volatiles into a bubble and therefore increase the pressure in a closed syste~. The dynamic strain of either distant regional tectonic earthquakes or local volcanic tremor can be translated to static strain inside a magma chamber via this pro·cess. We formulate a theory appropriate to the conditions of a magma chamber an...

The importance of liquid evaporation on rectified diffusion processes

This paper unveils the basic mechanisms underlying rectified diffusion processes. The exact solution of the radial transport of species in both phases, gas and liquid, turns to be crucial to accurately predict the growthrate in the context of lithotripsy. The Direct Numerical Simulation of the temporal evolution of an spherical bubble is used to gain new insight on the effect of two phenomena: ...

Seismic triggering by rectified diffusion in geothermal systems

Widespread seismicity was triggered by the June 28, 1992, Landers California, earthquake at a rate which was maximum immediately after passage of the exciting seismic waves. Rectified diffusion of vapor from hydrothermal liquids and magma into bubbles oscillating in an earthquake can increase the local pore pressure to seismically significant levels within the duration of the earthquake. In a h...

Sonoluminescence and Sonochemistry

Sonoluminescence and bubble fusion*

Sonoluminescence (SL), the phenomenon of light emission from nonlinear motion of a gas bubble, involves an extreme degree of energy focusing. The conditions within the bubble during the last stages of the nearly catastrophic implosion are thought to parallel the efforts aimed at developing inertial confinement fusion. A limited review on the topic of SL and its possible connection to bubble nuc...
