Abstract
Understanding the combustion of liquid fuels poses a complex challenge in thermal physics due to the interconnected nature of the various processes involved. It is becoming increasingly crucial to rely on computer-based experiments for understanding combustion and creating innovative burning-related devices. It may have increased importance in the role. In thermal physics, there is a growing trend toward utilizing computer-based techniques to study liquid fuels, offering the potential to enhance experiments through numerical simulations. This research involved conducting computerized experiments to understand the process of fuel combustion and the transformation into gas, focusing on the initial fragmentation and combustion stages. As a result of the computational experiments, the correlation between the temperature change of burning droplets, their size, and injection speed was investigated. Also, visual representations were created to demonstrate the dispersion of various fuel droplets in a combustion chamber. The obtained numerical calculations of the droplets' Sauter mean diameter distributions of 50 cm away from the nozzle of the injector were compared with experimental points, because of which the test demonstrated the accuracy of the numerical data for dodecane. The optimal combustion mode of octane and dodecane was established based on computer experiments to study the amount of fuel present and its temperature in a two-phase liquid system
