The article describes turbulent combustion in the front of a spherical flame of the fuel-air mixture in a spark-ignition engine. The paper considers two mathematical models of the workflow : a well-known “entrainment or eddy burning model” and a “laminar model of turbulent combustion” in the authors’ version of this paper. Both models are based on the Damköhler hypothesis (Damköhler G., 1940) on the turbulent combustion of gas, but have a significant difference in the mathematical formulation. Although both models contain empirical parameters, the authors’ model is much simpler and clearer. In numerical simulation, both mathematical models produce similar results. The authors also propose a “combined mathematical model of frontal turbulent combustion”.
