Description
Description
The present problem simulates the premixed combustion in a combustion chamber by ANSYS Fluent software. In the present case, it is assumed that the fuel and air enter the chamber from one boundary and hence are considered premixed.
The geometry of the present model is two-dimensional and has been designed using Design Modeler software. We do the meshing of the present model by ANSYS Meshing software. The mesh type is Structured, and the element number is 86,002.
This CFD project is the 4th episode of the Combustion Training Course.
Premixed Combustion Methodology
The species transport model is used to model the combustion process. The one reaction methane-air mixture is selected, and the volumetric option is used to model combustion in the chamber.
Also, the Eddy Dissipation / Finite Rate model is enabled to account for the turbulence chemistry interactions. This submodel neglects the detailed kinetic mechanisms and only considers the effect of mixing on combustion.
Also, the Energy equation is On to calculate the changes in temperature due to the combustion process, and the Viscous is set as the Standard k-epsilon model.
Premixed Combustion Conclusion
After the simulation process was finished, contours such as temperature, velocity, different species’ mass fractions, and streamlines are obtained. As shown in the temperature contour, the temperature has clearly increased in the chamber indicating that the combustion has taken place.
Also, the formed secondary flows in the chamber are shown in the streamlines. These secondary flows have the role of increasing the mixing process between fuel and air and hence enhancing the combustion process.

What analysis type did the admin use for observing the simulation results, and how can one interpret it effectively?
MR CFD Support –
The admin used a post-processing analysis tool within ANSYS Fluent to observe the simulation results. They checked the temperature, velocity, species mass fractions, and streamlines to effectively interpret the combustion process within the chamber. By examining the temperature rise shown in the contours, one can identify where the combustion is happening. Secondary flows observed in the streamlines indicate how the fuel and air mix, which is crucial for understanding combustion efficiency.

Mr. Brycen Grady DVM –
The description mentions the use of a single reaction methane-air reaction. Can you explain how this simplification affects the accuracy of the simulation results, particularly with regards to the chemical complexity of real combustion processes?
MR CFD Support –
The single reaction methane-air mixture simplification in the simulation focuses on capturing the essential characteristics of the combustion process while omitting complex chemical kinetic mechanisms. This approach generally results in faster computations at the expense of some accuracy, particularly in situations where detailed reaction mechanisms play a key role in the combustion dynamics. However, for many engineering applications, this level of simplification is deemed acceptable to gain insights into the overall process with reasonable accuracy and computational efficiency.

Joel Ruecker –
This training content seems very comprehensive, but I am curious about how the Finite Rate model affects the simulation compared to using the Eddy Dissipation model alone. Could you elaborate on that?
MR CFD Support –
When using the Finite Rate model in conjunction with the Eddy Dissipation model in ANSYS Fluent, it allows for a more realistic simulation of the combustion process. The Eddy Dissipation model primarily focuses on the turbulence effects on the reaction rates, while the Finite Rate model takes into account the chemical kinetics of the reactions. This combination provides a balance between simulation accuracy and computational cost by capturing the effects of both turbulence and chemistry-controlled reaction rates on combustion.

Rachael Pacocha –
This training product seems comprehensive. The emphasis on the mixing process and its necessity for enhancing combustion is appreciated; were the resultant emissions from the combustion analyzed in the simulation as well?
MR CFD Support –
In our premixed combustion simulation, we focus primarily on factors that affect the combustion process, like flow mixing and temperature distribution. However, emissions analysis can be a separate, complex area and may require advanced models for accurate prediction of species such as NOx or CO. For this specific training, emission analysis was not mentioned, but additional modules or supplements may provide insights into this aspect of combustion simulation.
