Description
Premixed Combustion, Species Transport, Eddy Dissipation, ANSYS Fluent CFD Training
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 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 with ANSYS Meshing software. The mesh type is Structured, and the element number is 86,002.
This CFD project is the 3rd 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 model accounts 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 were obtained. As shown in the temperature contour, the temperature has 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.

Issac Mayert –
I’m really impressed with the way the secondary flows are displayed to enhance understanding. Do these flows give a realistic perception of acceleration within the chamber?
MR CFD Support –
Thank you for your kind words! Secondarily flows are crucial in a combustion chamber as they help to promote thorough mixing of fuel and air, thereby ensuring efficient combustion. The simulation aims to provide a realistic view of the behavior of these flows and their contribution to the acceleration of particles within the combustion process. We’re glad that this aspect of the simulation was clear and insightful for you.
Mitchell Stamm –
The combination of structured mesh and the species transport model was well-explained, but I’d like to know if other turbulence models were considered for this simulation, and if so, why the k-epsilon model was chosen?
MR CFD Support –
For this particular simulation, the k-epsilon model was chosen because it provides a good balance between accuracy and computing resources for industrial applications involving combustion. Other turbulence models, such as k-omega or RNG k-epsilon, might also be suitable, but the standard k-epsilon model is well-established for a wide range of turbulent flows and is less computationally intensive, which potentially reduces the simulation time while still capturing the essential physics of the combustion process.

Mr. Conor Abshire DDS –
Is the temperature rise consistent across the entire chamber, or are there hot spots?
MR CFD Support –
In this simulation, the temperature increase is not perfectly uniform across the entire chamber. As presented in the temperature contour, there are areas with higher temperatures indicating that combustion mainly occurs in distinct zones, creating ‘hot spots.’

Edwin Bogan –
I’m amazed by the detail in the simulation results! How does the inclusion of the eddy dissipation model specifically affect the accuracy of simulation in premixed combustion cases?
MR CFD Support –
Thank you for the kind words! The eddy dissipation model in the premixed combustion simulation predominantly affects the predicted rates of reactions. It simplifies the impact of turbulence on the chemical kinetics by assuming that the reaction rate is controlled by the rate of eddy dissipation, which embodies the mixing process of reactants. This approach, while less detailed than solving full kinetic models, provides a good balance between computational resource requirement and the accuracy of capturing key features of turbulence-chemistry interactions in combustion. The model’s integration greatly contributes to correctly predicting the reaction zone’s location and overall combustion behavior.
Axel Langosh –
The breakdown of how combustion is affected by eddy dissipation would help further my understanding. Could you please clarify that part?
MR CFD Support –
In the simulation, the eddy dissipation model estimates the combustion rate based on the turbulent mixing time scale and the reactants’ concentration. Essentially, it is based on the assumption that the reaction rate is limited by the speed at which reactants are brought together by the turbulent flow, which is the mixing-controlled rate. Consequently, reactions occur only within the eddies where fuel and oxidizer concentrations are at molecularly mixed conditions. Therefore, the rate of combustion depends largely on turbulence characteristics rather than detailed chemistry mechanisms. When the combustion products move out of these fine structures, they are then governed by molecular diffusion.

The training course sounds detailed! Was there an improvement in combustion efficiency due to the secondary flows created within the chamber? I’m curious about how these patterns in flow can influence the overall process.
MR CFD Support –
As an admin, I cannot provide real-time feedback since I don’t have the data post simulation. However, typically, the secondary flows are beneficial as they enhance the mixing of the fuel and air, leading to more uniform combustion and potentially increasing efficiency. In simulations like these, the detailed results and analysis would explain exactly how much efficiency is gained through such flow patterns.

Rhianna Lueilwitz –
The premixed combustion simulation scenario with eddy dissipation clearly presents complex interactions between turbulence and chemical kinetics. Could you elaborate on how this model is advantageous for simulating a realistic combustion chamber?
MR CFD Support –
The use of the eddy dissipation model is advantageous for simulating realistic combustion chambers because it simplifies the chemistry of turbulent premixed flames. It assumes that the rate of combustion is controlled by the rate of mixing rather than by the rate of chemical reaction. This assumption significantly reduces computational costs while still providing reasonable accuracy for the temperature and species concentration predictions within the combustion chamber.
