Acoustic bubble sizing by combination of subharmonic emissions with imaging frequency
The non-linear response of a bubble to an acoustic field results in the scattering of sumand difference-frequencies when two frequencies are incident. This has in the past been used to size bubbles. since it is only when the pump frequency. wp' is near the bubble resonance that the non-linear effects are observed. In addition. the subharmonic frequency emitted by the bubble can combine with the...
متن کاملLight Transfer in a Bubble Sparged Photobioreactor for Simultaneous Hydrogen Production and CO2 Mitigation
This paper presents a parametric study of light transfer simulations in a rectangular photobioreactor containing gas bubbles and cyanobacteria Anabaena variabilis suspended in water. To the best of our knowledge, this paper presents for the first time a model for such system (i) using a consistent set of radiative properties of the medium derived from experimental data and from Mie theory, (ii)...

This paper presents a parametric study simulating light transfer in a photobioreactor containing gas bubbles and filamentous cyanobacteria Anabaena variabilis suspended in water. To the best of our knowledge, this paper presents for the first time a model for such system: (i) using a consistent set of radiation characteristics of the medium derived from experimental data and from Mie theory; (i...
متن کاملBubble cluster dynamics in an acoustic field.
A mathematical model describing dynamics of the cluster of gas bubbles in an acoustic field is presented. According to this model a cluster is considered as a large drop with microbubbles inside. The proposed model is used as a basis (1) for an analytical study of small bubble oscillations in mono- and polydisperse clusters and (2) for numerical investigations of nonlinear bubble oscillations a...
متن کاملSimulation of bubble motion in acoustic cavitation
The many particle problem of moving cavitation bubbles in a liquid exposed to ultrasound need certain ingredients: Besides N bubbles and their positions ~xi and velocities ~ui, one has to specify the bubble sizes and shapes. Mechanisms for nucleation and annihilation or coalescence of bubbles have to be introduced, and a sound field distribution has to be given. Additionally, a liquid motion ca...
