Increasing the efficiency of gasoline combustion depending on the spray angle in a model combustion chamber

Abstract

This article presents the results of numerical simulation that evaluates the influence of the spray angle of gasoline (С6Н6) in the combustion chamber on the temperature distribution in the combustion chamber and the formation of carbon dioxide concentration. The purpose of this work is to study the influence of initial parameters on the process of liquid fuel combustion using numerical simulation based on the solution of two-dimensional differential equations of turbulent reacting flow. The studies were carried out at spray angle of 20-160 using the KIVA-II software package. Analyzing the results of the study, the value of the effective spray angle for gasoline combustion was determined. At an effective spray angle of 60, the temperature in the chamber rises to 2467 K, in which case the concentration of carbon dioxide acquires a relatively small value.
