Název v původním jazyce

Acoustic streaming in resonators with heated walls

Popis výsledku v původním jazyce

Acoustic streaming in fluid-filled resonators with the spatial distribution of walls’ temperature is studied within this work. The method of successive approximations is employed to derive linear equations for the calculation of ambient, 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 COMSOL Multiphysics. The numerical results are validated for the case of a resonator with spatially-constant ambient temperature by comparison with previously published analytical results; an excellent agreement is found. Examples of acoustic streaming structures in resonators with heated walls are given showing a strong influence on the walls’ temperature distribution and the resonator cavity dimensions.
