Mixed finite elements applied to acoustic wave problems in compressible viscous fluids under piezoelectric actuation

In the present contribution, we develop a mixed finite element method capable of the coupled multi-field simulation of a viscous fluid actuated by a piezoelectric resonator. Several challenges are met with in this setting, among which are the necessity of correct interface coupling, near incompressi...
