In recent years, the Lattice Boltzmann Method (LBM) has been demonstrated as an interesting alternative for the simulation of complex fluid flows. Unlike finite elements models (FEM) based on a discretization of macroscopic continuum equations, the LBM is derived from microscopic models and mesoscopic kinetic equations . As an increasing number of studies use acoustic standing waves for microfluidics applications , the LBM constitutes an efficient alternative to simulate complex interactions between fluid flows and acoustic waves. The main advantages include clear physical pictures, easy implementation of boundary conditions and a fully parallel algorithm. This paper shows results towards the implementation of LBM for the creation of acoustic standing waves in straight microchannels.
