“…Also, as a result of assuming a small relative motion due to the viscosity of the gas, the shape of the small droplets becomes close to a sphere. The self-ignition temperature of liquid fuels is always higher than their boiling point, because of this, the combustion of liquid fuels is possible only in the vapor state in the presence of an oxidizing agent [2]. The burning rate depends on the nature of the movement of gases.…”

In this work, the ignition of liquid fuel was studied at various rates of fuel injection into the combustion chamber. The studied processes are described by the following equations: continuity, momentum, energy, k-ɛ turbulence model and others. The computational experiment was carried out using the KIVA-II software. The numerical method is efficient and takes into account various factors such as multistage chemical chain reactions, transfer of momentum, heat and mass by convection, radiation, turbulence, etc. In order to select the optimal parameters of the organization of these processes influence of the heptane injection rate into the combustion chamber on the process of combustion and self-ignition of heptane was studied. The injection rate of heptane varied from 160 m/s to 400 m/s an interval of 30 m/s. The size and temperature distributions of heptane droplets before evaporation, the concentration fields of carbon dioxide, and the temperature fields in the combustion chamber depending on the rate of fuel injection through the injector into the combustion chamber were obtained. The optimal range of heptane injection speed was determined, which is 250 m/s - 280 m/s, in order to increase the efficiency of the combustion chamber and reduce the negative impact on the environment.

“…Согласно мировой статистике, 40% общего потребления энергии достигается за счет сжигания жидкого топлива. Поэтому одним из важных вопросов на сегодняшний день является всестороннее изучение процесса горения и рассмотрение методов снижения количества вредного воздействия, выделяемого в процессе горения [1][2][3][4].…”

Аннотация. В данной статье проведен анализ результатов численного исследования влияния начальной массы впрыска и начальной температуры окислителя на процесс горения тридекана (C13H28). В ходе исследовательской работы был использован программный пакет KIVA. На основании результатов проведенного численного моделирования получено распределение температуры капель топлива и концентрации CO2 при различных значениях массы впрыскиваемого жидкого топлива в камере сгорания.Проанализировав результаты исследования, выяснилось, что эффективная начальная масса впрыска топлива равна 9 мг. Изучив зависимость максимальной температуры и концентрации углекислого газа в камере сгорания, образующейся в результате горения топлива, от начальной температуры окислителя в камере сгорания, был сделан вывод о том, что значение эффективной начальной температуры окислителя равно 900 К.Ключевые слова: численное моделирование, жидкое топливо, тридекан, камера сгорания, KIVA, масса, температура. 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.
