Direct modeling method of acoustic streaming using lattice Boltzmann approach

Abstract

This paper introduces a numerical analysis of the acoustic streaming phenomenon using the lattice Boltzmann method (LBM). This study aims to investigate the flow created by the sound wave propagation in water. The waves are emitted by a linear source situated in the middle of the left surface of a rectangular cavity. This acoustic streaming study can be applied in the photovoltaic silicon purification field whose final objective is the participation in the manufacture of photovoltaic panels. This work is particularly interested in the study of Eckart streaming produced by the dissipation of the waves acoustic energy in the medium. An analytical analysis is also performed to confirm the validity of the numerical approach.
