Abstract: A new model of a laminar combustion process is constructed based on its thermodynamic analysis. Under controlled growth of temperature at the inlet to the combustion chamber, depending on the structure of the standard chemical potential, high-frequency oscillations of the thermal explosion resonance occur in the model. Resonance modes in the case of heat pumping are modeled, the nature of their origin is established depending on the structure of the standard chemical potential, and numerical experiments exhibiting these modes are presented.

Keywords: thermodynamic analysis, mathematical models of combustion process, local equilibrium, laminar combustion process, high-frequency oscillations.
