abstract = {<p style="text-align: justify;">This paper presents a lattice Boltzmann (LB) method based study aimed
at numerical simulation of aeroacoustic phenomenon in flows around a symmetric
obstacle. To simulate the compressible flow accurately, a potential energy double-distribution-function
(DDF) lattice Boltzmann method is used over the entire computational
domain from the near to far fields. The buffer zone and absorbing boundary
condition is employed to eliminate the non-physical reflecting. Through the direct numerical
simulation, the flow around a circular cylinder at $Re$=150, $M$=0.2 and the
flow around a NACA0012 airfoil at $Re$=10000, $M$=0.8, $α$=$0^◦$ are investigated. The
generation and propagation of the sound produced by the vortex shedding are reappeared
clearly. The obtained results increase our understanding of the characteristic
features of the aeroacoustic sound.</p>},
