Thermo-acoustic instabilities represent a major technical problem in many combustion applications and are generally manifested as large-amplitude pressure oscillations coupled with unsteadiness in the combus-tion processes. In the present analysis, the interaction of acoustic waves with planar counterflow methane-air premixed flames is investigated numerically for a range of flow strain rates and flame locations, and em-ploying a detailed and one-step global finite-rate kinetic models. It is found that one-step global models with large activation energy always promote the amplification of acoustic pressure fluctuations in counter-flow premixed flames, whereas the detailed kinetic model exhibits thermo-acoustic instabilities for specific loc...
