Two-Phase Frequency domain analysis?

I am trying to model the reaction of a bubble to an acoustic wave, and have successfuly done it in time domain.

Is there a way to use two-phase flow anaylisis (ideally moving mesh) with a linearized version of Navier-Stokes, using perturbation analysis?

I see a linearized version of the Navier-Stokes equations in the aeroacoustics module, but no way of coupling that to any of the two-phase alternatives. Any help or insight as to why that cannot be done is welcome.
