Computer modeling of the effect of speed on the process of injection combustion of liquid fuels of various types at high pressures

Abstract

Combustion liquid fuels is a complex task, as it characterized by a number of specific features, due to chemical reactions under conditions of dynamic and of thermal interaction between reagents, the intensive mass transfer during phase transformations, as well as the dependence of the process parameters, such as the thermodynamic state of the system and of its structural characteristics. So numerical simulation can be successfully used to predict and study the behavior of complex systems, which has received more widespread in thermal physics. The paper is presented the mathematical model and the basic equations describing the liquid fuel combustion process at high turbulence. There are conducted computational experiments on the combustion of liquid fuel according to the fuel injection velocity into the combustion chamber at the initial conditions. Velocity and pressure profiles in the combustion chamber for two liquid fuels are built.
