| Research Abstract |
In order to explore behavior of the near extinction flamelet in turbulent premixed flames, relation between the emission intensity ratio of 515/470nm band of C2 (C2*(0,0)/C2*(1,0)) and the flame temperature for various strain rates has been sought in both unstrained and strained flames by using a rectangular nozzle burner and a counter-flow burner, respectively. For strained flames, as the strain rate increases with the equivalence ratio of the mixture is constant, the flame temperature decreases, and C2*(0,0)/C2*(1,0) decreases slightly
