Abstract

Fractal burning model was applied to the simulation of combustion in a spark-ignition engine. This model was examined under various conditions of swirl intensity in a disk-type combustion chamber. The computed results of mass fraction burned were in good agreement with experimental ones. In this model, the following relations were assumed. (1) The fractal dimension D₃ is expressed as a function of (ρ/ρ_r)(u′/S_L), where ρ/ρ_r, u′, and S_L are density ratio, turbulence intensity, and laminar burning velocity, respectively. (2) The outher cutoff scale is equal to the flame radius, and the inner cutoff scale is proportional to Kolmogoroff scale.
