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 the greatest combustion temperatures can attain levels of up to 2700 K, signifying both high energy effectiveness and strong combustion stages. Furthermore, this extent of Reynolds number results in a notable decrease in soot particles (75-50 g/g), indicating a more thorough fuel combustion process and enhanced oxidative conditions. The outcome data affirms that expanding Reynolds numbers elevate combustion temperatures and improve biodiesel’s environmental efficiency by diminishing the emanations of solid burning byproducts. This inquiry highlights the biodiesel promise as a sustainable and eco-friendly substitute for conventional hydrocarbon fuels, offering optimal combustion characteristics under high turbulence conditions.
