The Bray-Moss-Libby model of premixed turbulent combustion is modified to account for unsteady problems with variable enthalpy. Nonconstant thermodynamic properties are also included. A numerical solution procedure is applied to the model equations and a one-dimensional test problem is solved. Four separate test cases are used to demonstrate the integrity of both model and solution procedure. Countergradient transport and flame-generated turbulence are both predicted to occur as a result of an interaction between density fluctuations and the mean pressure gradient. However, in the cases studied, these effects are found to be smaller than in stationary unconfined planar flames.
