dc.description.abstractDirect numerical simulation (DNS) is used to study sound generation by open, turbulent premixed flames. Two cases of methane/air combustion with different equivalence ratios (φ = 0.7 and 1 ) are considered. The computational grid is set up such that both the near and far fields are fully resolved. A simple-chemistry model is used to reduce the computational cost. The results show that flame annihilation events are significant monopolar sources of noise. Spectral analysis of the radiated sound shows a broadband spectrum where the observed frequency of the peak amplitude matches that observed experimentally. Furthermore, it is observed that the stoichiometric flame (φ =1) is a much stronger source of noise than the lean flame (φ = 0.7 ).
