This work aims to characterize the effects of forced acoustic waves onto a weakly turbulent premixed methane/air flame. These acoustic waves are generated by means of a loudspeaker and injected into the combustion chamber coaxially. The experimental characterization is performed by using synchronized PIV and PLIF techniques, the last based on OH+ emission. The interaction between the forced acoustics and combustion is examined in terms of macroscopic effects, as velocity and vorticity fields.
