Description

Description

The present problem simulates the non-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 distinct 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 with ANSYS Meshing software. The mesh type is Structured, and the element number is 63280.

This CFD project is the 4th episode of the Combustion Training Course.

Non-Premixed Methodology

Non-premixed combustion model is used to model the combustion process. Non-adiabatic energy treatment and a steady diffusion flamelet model are used to model the combustion process.

First, a Chemkin mechanism is read in Fluent and used to create the flamelet (models a turbulent flame brush as an ensemble of discrete, steady laminar flames).

Next, a PDF table is generated to store data related to changes in temperature, density of mixture, and different chemical species mass fractions before 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 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.

    I’m amazed by the detail in the combustion simulation! Could you clarify if the PDF table affects the computation speed or accuracy in this simulation?

      Thank you for your kind words! The use of the PDF table actually makes the simulation more efficient and accurate. It allows the pre-computation of complex chemistry and thermochemical properties, which can be quickly accessed during the simulation. This leads to reduced computation times while maintaining a high level of accuracy for non-premixed combustion scenarios.

    How does the steady diffusion flamelet model differ from other combustion models, and why was it chosen for this scenario?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The steady diffusion flamelet model is designed to simulate combustion processes where fuel and oxidizer are not premixed. It simplifies the chemistry by assuming that turbulence affects the mixing process but does not affect the chemistry directly. This is different from other models, like the Eddy Dissipation Concept or the Laminar Finite-Rate model, which might account for turbulence-chemistry interaction more directly. It was likely chosen for this scenario as it’s computationally efficient for modeling the mixing and combustion of distinct streams of fuel and air, which is the case in non-premixed combustors.
