Description
Description
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.
Vortex Methodology
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.
Vortex Conclusion
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.

Camila Lindgren –
how does the simulation figure out the liquid dance in the combustion chamber?
MR CFD Support –
Well, the simulation has a pretty solid fluid dynamics model. It’s really good at catching how the fluid moves around in the combustion chamber, even when it starts doing the twist and turn thing, you know, creating vortices.
Dr. Agustin Wuckert Sr. –
So, how’s the simulation dealing with the nasty stuff released during combustion?
MR CFD Support –
Well, the simulation has got this cool model that really nails down how much of the bad stuff gets out during combustion. It’s super important for understanding how well the combustion chamber is doing its job.
Humberto Kuphal I –
Can the simulation model the effect of different types of fuel on the combustion process?
MR CFD Support –
Yes, the simulation can be adjusted to model different types of fuel, which can significantly affect the combustion process and the performance of the combustion chamber.
Dr. Gerhard O’Kon –
How does the simulation model the combustion process in the vortex combustion chamber?
MR CFD Support –
The simulation uses a detailed combustion model that accurately captures the combustion process in the vortex combustion chamber, including the chemical reactions and heat release.
Rashad Johnston –
How does the simulation handle the emission of pollutants from the combustion process?
MR CFD Support –
The simulation includes a model that accurately captures the emission of pollutants from the combustion process, which is a critical aspect of the performance of the combustion chamber
