Abstract

The problem of flame propagation over premixed gas mixtures is analyzed using the principle of minimal entropy production. The flame propagation velocity predicted by a general approach based on the integral mass balance is considered as an exact physical solution corresponding to the actual stationary regime of flame propagation. The difference between the actual stationary state of the system and the state with minimal entropy production has been estimated. An adequate physical description of the flame propagation phenomenon by the approach, assuming that the stationary state is characterized by minimal entropy production, has been obtained for a variety of physical and kinetic parameters.
