It is shown that the detailed structure of a flat laminar opposed jet diffusion flame can be modeled, by properly coupling the momentum and energy conservation equations and by using detailed finite rate combustion kinetics. Such a flame is one dimensional (for a given stretching rate) provided that the proper velocity boundary conditions, which are a result of the model are employed. A laboratory CH/sub 4//N/sub 2//O/sub 2/ opposed jet diffusion flame was realized and gave good agreement with predictions with respect to both, one dimensionality and the temperature and species profiles within the reaction zone. However, the actual location of the reaction zone was displaced by a small distance. The qualitative dependence of the NO profile on flame stretching was correctly predicted by the model. 12 refs.
