The present problem simulates the non-adiabatic 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 separate boundaries and hence are considered Non-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 63280.

This CFD project is the 3rd episode of the Combustion Training Course.

Non-Premixed Combustion Methodology

Non-premixed combustion model is used to model the combustion process. Non-adiabatic energy treatment along with a chemical equilibrium model is used to model the combustion process.

A PDF table is generated to store data related to changes in temperature, density of mixture, and different chemical species mass fractions prior to simulation to be used during the main calculations.

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.

Non-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.
