Abstract

The effect of hydrogen addition to methane on premixed turbulent flame has been investigated. Lean, stoichiometric and rich flames have been tested using a Bunsen burner at 3 bar and 7 bar absolute pressures, and 473 K, 573 K and 673 K temperatures. Two important turbulent flame structure characterstics, namely flame brush thickness δ T and flame surface density Σ have been quantified and analysed. Coefficients of the equations which relate flame brush thickness with progress variable are deduced. Flame surface density and the Bray-Moss-Libby model coefficient g/(σ y L y ) for the fuel mixtures studied have been found.
