  • Experimental Study on Turbulent Burning Velocity of Hydrogen Mixtures

説明

Turbulent burning velocity characteristics of hydrogen mixtures with having the same laminar burning velocity are investigated experimentally in the present study, where the laminar burning velocity S_<L0> and the equivalence ratio Φ are varied extensively. The measured turbulent burning velocity at the same turbulence intensity shows to increase as Φ decreases, regardless of S_<L0>. That, however, becomes to depend on the characteristics chemical time when Φ is as low as around 1.0. This phenomenon is discussed by the estimated mean local burning velocity taking account of the preferential diffusion effect and the obtained turbulent flame images.
