Numerical research of the influence of initial parameters on the process of tridecane combustion in the combustion chamber

Abstract

This article analyzes the results of a numerical study of the effect of the initial injection mass and the initial temperature of the oxidizer on the tridecane (C₁₃H₂₈) combustion process. During the research work, the KIVA software package was used. Based on the results of the performed numerical simulation, the distribution of the temperature of the fuel droplets and the concentration of CO₂ were obtained for various values of the mass of injected liquid fuel in the combustion chamber. After analyzing the results of the study, it turned out that the effective initial mass of fuel injection is 9 mg. Having studied the dependence of the maximum temperature and concentration of carbon dioxide in the combustion chamber, formed as a result of fuel combustion, on the initial temperature of the oxidizer in the combustion chamber, it was concluded that the value of the effective initial temperature of the oxidizer is 900 K.
