Title of the articleMathematical model of soot formation in the flame of a homogeneous hydrocarbon-air mixture
Abstract.Problem statement. The aim of the study was to determine the effect of coagulation of soot particles and the initial air temperature on the mass yield of soot, to determine the dependence of the average diameter of soot particles on residence time, and to determine the effect of the heat sink on the dependence of the mass yield of soot on the composition of the air-fuel mixture. Results. The main results of the study consist in the development of a mathematical model for soot formation in the flame of a homogeneous hydrocarbon-air mixture. On the basis of this model, the authors have obtained the role of coagulation of soot particles in the soot formation process, by analyzing the calculation with and without coagulation. Conclusions. The significance of the obtained results for the construction industry is that on the basis of numerical modeling, the effect of gasification processes of soot particles on the reactions to the change in mass yield of soot during fuel combustion is predicted and taken into account, for example, in the utilization of solid household and construction waste, since ignoring these processes leads to Significant errors, and as a result, pollution of the environment. The calculated model allows us to study, on the basis of numerical experiments, the effect of the combustion parameters on the soot formation threshold.
Keywords.loss of thermal energy, mathematical model of soot formation, coagulation, composition, temperature.
