coupling fluid flow with acoustics

Hi, everyone

I would like to know what velocities of a fluid are produced by the vibration of a probe submerged in it. I have already done transient acoustic modeling, where the pressure distributions are found within the fluid. One of the probe boundaries was defined as normal acceleration. However, I am interested in the velocity fields of the fluid. Is it possible to take the pressure as an input for the fluid flow? How can I achieve this? Any ideas?

Thank you
