Due to the high level of achieved research, there are prospects for the widespread use of the method andspecific physical results in the areas under consideration, as well as ways for more effective applicationof mathematical modeling methods using modern computing technology in various subject areas. For thenumerical study of the combustion of liquid fuels, it is required to consider many complex interrelatedprocesses and phenomena, which are laborious tasks of computational thermal physics. In the theory’s studyof combustion and the development of various technical devices, the actions of which are based on the useof the combustion process, a computational experiment is becoming an increasingly important element.Computational fluid dynamics methods have become widespread in technical physics when it becomespossible to optimize an experiment based on its virtual prototype. This work is devoted to the numericalmodeling of the processes of breakup, dispersion, evaporation and combustion of liquid fuel droplets underhigh turbulence. Fundamental characteristics, methods of liquid fuels atomization, the mathematical modeland basic equations describing the collision, distribution and combustion of liquid fuels at high turbulenceare presented. Results of computational experiments by determination of the optimal conditions for thecombustion of liquid hydrocarbon fuel are presented. Influence of the oxidant’s initial temperature on theprocesses of atomization and dispersion of droplets in the combustion chamber under high turbulence isinvestigated. Optimal combustion parameters for the dodecane have been determined. Key words: numerical modeling, atomization, liquid fuel, dodecane, high turbulence.
