AbstractMany studies have been devoted to the structures and propagation of triple flames. However, fewer studies on NOx formation in triple flames have been reported. It has been shown that NOx formation in a flame is closely related to the flame structure. Our recent study on NOx formation in methane/air triple flames showed that the mechanism of NOx formation in a triple flame is different from in either a premixed or a diffusion flame, due to the specific structure of a triple flame. n-Heptane is a relatively heavy hydrocarbon fuel that is generally used to simulate a diesel combustion. The purpose of the present paper is to numerically investigate NO, the dominant component of NOx, formation in n-heptane triple flames. The discussions first focus on the results for two typical triple flames that exhibit the most significant features of triple flames. Then the effects of the variation in the equivalence ratio of the lean or rich mixture and the stretch rate will be examined.
