The Lattice Boltzmann Method (LBM) is a numerical method used at the mesoscopic scale to simulate different physical phenomena. It is also one of the useful tools for simulating the propagation of waves in complex media.

This study carried out on the influence of thermal convection on the propagation of acoustic waves using the Multi-Relaxation time (MRT) method. The D2Q9-MRT is applied to calculate the macroscopic quantities such as the density of fluid, the velocities and the pressure, while the D2Q5-MRT is used to solve the temperature field. The main idea is to highlight the change produced by thermal convection on the propagation of acoustic waves in air.
