Abstract
A numerical investigation was carried out in order to predict the effects of symmetric heating on irregular acoustic streaming in air-filled shallow enclosures. The fluid motion is driven by periodic vibration of the enclosure left wall. The vertical walls of the enclosure are adiabatic while the horizontal walls are heated symmetrically. A control-volume method based, explicit time-marching Flux-Corrected Transport Algorithm is used to simulate the transport phenomena in the enclosure. A symmetric temperature gradient strongly alters the irregular acoustic streaming structures and velocities. [ABSTRACT FROM AUTHOR]
