Abstract

We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.
