Effects of Acoustic Actuation on a Multi-Phase Jet
Résumé
In this contribution the effects of a nearly axisymmetric standing acoustic wave on the transport properties of a multi-phase jet are examined. The standing wave is seen to drive liquid droplets from the pressure anti-node , where the jet center-line is located towards the pressure node where the jet edge is located. Self-similarity of the gas-phase is modified in presence of the acoustics. Radial transport of the smallest particles is enhanced and saturation of this effect occurs as particle inertia increases. The overall volume flux profile of the jet is relatively unchanged but significant changes are observed in the number flux profile which is more sensitive to small particle dynamics. No evidence of enhanced atomization is observed, although the arithmetic mean diameter profiles are significantly altered due to modified transport.
