Abstract

Numerical research of burning of liquid fuels is a complex challenge of thermo physics as demands the accounting of a large number of the difficult interconnected processes and the phenomena. Therefore computing experiment becomes more and more important element of research of processes of burning and design of various devices using burning process. In work the mathematical model and the main equations describing process of burning of liquid fuels at high turbulence is stated. Research of processes of disintegration and dispersion depending on pressure and an initial lot of injection in the combustion chamber of liquid fuel is conducted: tetradecane. As a result of the made computer experiments dependences of the maximum temperature on pressure were received, distributions of carbon dioxide from a lot of injection, distribution of drops on radiuses and temperature fields at the optimum mode of burning.
