• In this paper, we simulate directly the Aeolian tone emitted from a two-dimensional circular cylinder by the finite volume lattice Boltzmann method (FVLBM) using the two-dimensional thermal compressible lattice BGK model with the internal degrees of freedom on unstructured grid. We also introduce a novel third-order upwind scheme for the FVLBM, using quadratic polynomials interpolating two distribution functions and a first differential coefficient of distribution function, and by means of this, we obtain accurate results of the simulation of the acoustic waves that agree well with those by the very accurate computation based on the Navier-Stokes equation using the scheme with higher order accuracy. We show the applicability of the FVLBM to the direct simulation of aerodynamic sound from more complex shaped bodies on unstructured grid.
