In this project, a combustion reaction is simulated inside a vortex combustion chamber by ANSYS Fluent software.
Combustion is the result of a chemical process between combustible material and an oxidizing agent that is associated with the production of heat and the chemical change of raw materials in a combustion chamber.
Heat can be released by producing light in the form of a flame or a glow. Fossil fuels are usually made of organic compounds in the form of gases, liquids, or solids.
As mentioned above, burning is a type of oxidation reaction. However, due to the high speed of the combustion reaction, which leads to the production of a high amount of heat in a short time, the increase in the ambient temperature, and the creation of light and flame, it falls into a special category.
The vortex combustion chamber is a new generation of liquid fuel internal combustion engines in which, a whirlpool flow is created with a different arrangement of injectors.
This whirlpool helps to cool and increase the mixing of propulsion components in the combustion chamber, and complete combustion can be reached in smaller volume chambers.
The geometry of this project is designed and meshed inside GAMBIT®. The mesh type used for this geometry is unstructured and the total element number is 379535 cells.
The species transport model is used to analyze the combustion process. A mixture of air and methane is used as the fuel mixture. Eddy-Dissipation method has been used to investigate the chemical-turbulent interaction of combustion reactants and the NOx anticipation model is activated and the Temperature method is used for Turbulence Interaction mode. The ideal gas equation has also been used to determine the density changes due to changes in temperature.
Different contours of velocity, pressure, temperature, species mass fraction, etc. are presented in 3D and 2D. As can be seen from the contours, the combustion flame is well formed and the temperature changes caused by the combustion are well visible.
The vectors also show that the flow turbulence in this problem is very high. The contours show that this indicates that the performance of this combustion chamber has been simulated correctly.
