The Overall Reaction Concept in Premixed, Laminar, Steady-State Flames. II. Initial Temperatures and Pressures.
Abstract
In a previous report, we examined the adequacy of the overall reaction model for premixed, laminar, one-dimensional, steady-state flames. The single reaction model gave quite accurate results for burning velocity. The temperature and heat release profiles were also generally accurate. The accuracy of the major species profiles varied from fair to good. However, the optimal overall kinetic parameters varied with the equivalence ratio. In this report, the adequacy of an overall reaction model for premixed, laminar, one-dimensional, steady-state flames is examined for variations in initial temperature and pressure. The single reaction model gives quite accurate results for burning velocity; temperature and heat release profiles are also generally accurate; major species profiles are reproduced with fair to good accuracy. The optimal overall parameters change with initial temperature and pressure. However, a single set of parameters are found to be accurate over a limited range of initial temperatures and pressures.
