Acoustic streaming in shaped resonators
Original language description
Acoustic streaming in fluid-filled resonators with variable cross-section is studied within this work. An inertial force is assumed for driving the acoustic field. The method of successive approximations is employed to derive linear equations for calculation of primary acoustic and time-averaged secondary fields including the mass transport velocity. The model equations have a standard form which allows their numerical integration using universal solver COMSOL Multiphysics. The numerical results are validated for the case of a resonator with constant cross-section by comparison with previously published analytical results; an excellent agreement is found. Example of acoustic streaming in a shaped resonator is given to demonstrate a strong dependence of the acoustic streaming structure on the resonator shape.
