The combustion processes of biodiesel droplets in a combustion chamber using numerical modeling of two-phase reacting flows and complex turbulent currents are investigated in this study. The focus is on analyzing temperature fields, aerodynamic characteristics, and soot particle distribution at varying Reynolds numbers. The results show that optimal combustion conditions for biodiesel are achieved at Reynolds numbers between 20,000 and 25,000, where maximum combustion temperatures reach up to 2700 K, indicating high thermal efficiency and intense combustion processes. Additionally, this range of Reynolds numbers leads to a significant reduction in soot particle concentration (50–75 g/g), suggesting more complete fuel combustion and improved oxidation conditions. The findings confirm that increasing Reynolds numbers not only enhances combustion temperature but also improves the environmental performance of biodiesel by reducing emissions of solid combustion products. This research demonstrates the potential of biodiesel as an environmentally friendly alternative to traditional hydrocarbon fuels, offering optimal combustion characteristics under high turbulence conditions.
