LATTICE-GAS AUTOMATON SIMULATION OF ACOUSTIC STREAMING IN A 2-DIMENSIONAL PIPE

The lattice gas automaton fluid modelling technique is used to study a coustic streaming phenomena arising from the interaction of sound wave s with no-slip boundaries in a two-dimensional pipe. It is demonstrate d that this fluid simulation tool is able to reproduce the general for m of the acoustic streaming flow field observed by Andrade [Proc. R. S oc. London 175, 1 (1883)] and predicted by Lord Rayleigh [Philos. Tran s. R. Sec. London 175, 1 (1884)]. The differences that are evident may be due to the restrictions on the computing resource which prohibits the use of a lattice large enough to fulfill the conditions used by Ra yleigh in his derivation of the acoustic streaming flow field.
