Comparisons were made of computed and measured flame fronts, flame tip propagation rates, and pressures for eight configurations of a divided-chamber, stratified-charge engine differing in speed, equivalence ratio, and throat area. In the model, conversion from reactants to products was assumed to be mixing limited so that the controlling processes were turbulence and wall effects. Turbulence was represented by a k #x2014; e model and wall effects by the #x201C;law of the wall#x201D; and Reynolds analogy. The results were also compared with those from earlier models that attempted to account for finite rate kinetics too, through one overall irreversible reaction.
