Description
Description
This simulation is about Non-Premixed Combustion via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
In this project, a two-dimensional combustion chamber is designed in which air flow and fuel flow enter simultaneously from two different inlets with different flow rates.
The combustion process occurs when some air is combined with some hydrocarbon fuel to convert fuel energy into heat energy. After the combustion occurs, the products of chemical reactions leave the combustion chamber.
Airflow (consisting of N2 with a mass fraction of 0.767 and O2 with a mass fraction of 0.233) at a temperature of 300 K and mass flow rate of 1.19 kg/s, and fuel flow (consisting of CH4 with a mass fraction of 1 At a temperature of 300 K and a flow rate of 0.019 kg/s) enter the combustion chamber through two separate and independent inlets to combine the chemical reaction of combustion to occur.
The geometry of the present model is drawn by Design Modeler software. The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 11202 cells have been created.
Non-Premixed Method
The Species model has been used in this numerical simulation to model the combustion and the chemical reaction. A non-premixed model has been used to define species composition.
In this type of combustion, fuel and oxidizer enter the reaction zone of the combustion chamber through separate paths; They do not mix (premix) before fully entering the combustion chamber.
The non-premixed combustion model defines the mixture fraction, which represents the mass fraction derived from the fuel flow. In other words, the mixture fraction is equivalent to the local mass fraction of fuel flow elements (such as C, H, etc.) in different species (such as CO2, H2O, O2, etc.).
Non-Premixed Conclusion
After simulation, 2D contours related to pressure, temperature, velocity, density, and mass fraction O2, CH4, H2O, CO2, N2, CO, and C2H6 are obtained.
Also, 2D pathlines inside the chamber are obtained. The results show that The combustion reaction occurred properly inside the combustion chamber.
As a result of the combustion reaction between the reactants (methane fuel and airflow), the products of the reaction, such as CO, CO2, H2O, etc., are produced.

How does the simulation handle the chemical reactions involved in non-premixed combustion?
MR CFD Support –
The simulation uses the Finite-Rate/Eddy-Dissipation model to handle the chemical reactions involved in non-premixed combustion. This model combines the detailed kinetics of the Finite-Rate model with the simplicity and robustness of the Eddy-Dissipation model, making it suitable for combustion simulations.
Adan Cormier –
Can this simulation be used to optimize the efficiency of combustion processes?
MR CFD Support –
Absolutely! By analyzing the combustion characteristics and identifying areas of inefficiency, this simulation can help in optimizing the design and operation of combustion systems, thus improving their efficiency.
Lila Schmitt –
I’m interested in using a different hydrocarbon for the fuel. Can non-premixed combustion simulations handle different fuels, and how would this affect the setup?
MR CFD Support –
Yes, non-premixed combustion simulations in ANSYS Fluent can handle a variety of fuels by updating the species transport and reaction mechanisms accordingly. When changing the hydrocarbon fuel, you need to configure the species’ properties and reaction kinetics based on the new fuel choice. This could also potentially affect the combustion temperature, reaction rates, and product species, so you would need to adjust inlet conditions and potentially the mesh for optimal resolution of the different flame characteristics.

Frederic Hettinger Sr. –
I’m quite fascinated by the use of two separate inlets for fuel and oxidizer in this non-premixed combustion simulation. Is this a common setup for industrial combustion systems, and what is the primary advantage of using segregated inlets over a premixed approach?
MR CFD Support –
Yes, using two separate inlets for the fuel and oxidizer in non-premixed combustion is common in industrial applications. The primary advantage is that it offers more control over the combustion process, improving efficiency and safety. In non-premixed systems, the mixture of fuel and air doesn’t occur until they reach the combustion zone, which allows for more stable combustion and reduces the risk of backfire. Furthermore, it can be beneficial for achieving higher temperatures and controlling emissions.

Jan Bode –
What are the main products of the combustion reaction in this simulation, and are the results showing any incomplete combustion phenomena such as the formation of CO?
MR CFD Support –
The main products of the combustion reaction in the simulation are CO2, H2O, and N2. The results also indicate the presence of CO, suggesting incomplete combustion phenomena. This could be due to various factors within the combustion chamber such as temperature gradients, mixing rates, or insufficient residence time.
Mr. Albin Torp –
The simulation explanation is quite detailed, but does it address possible pollutants created during combustion like NOx or SOx?
MR CFD Support –
The specific simulation outlined for Non-Premixed Combustion using ANSYS Fluent doesn’t explicitly mention tracking or analyzing the formation of pollutants such as NOx or SOx. It details the primary combustion products such as CO2, H2O, CO, and C2H6. To consider the formation of pollutants like NOx or SOx, specific models like NOx formation models would need to be included in the simulation setup.
Miss Loraine Farrell –
I’m intrigued by how the non-premixed combustion process is simulated. Could you clarify what distinguishes the non-premixed model from other combustion models in ANSYS Fluent?
MR CFD Support –
In the non-premixed combustion model used by ANSYS Fluent, fuel and oxidizer enter the reaction zone through separate paths and only mix when they reach the combustion chamber. This contrasts with premixed combustion models where the fuel and oxidizer are premixed before introduction to the combustion chamber. The disparity lies in the different control and influence over mixing and reaction rates, influencing flame stability, combustion intensity, and emissions.
Prof. Dudley Adams DDS –
This product makes the complex concept of non-premixed combustion quite easy to grasp. Through the detail oriented stages of this tutorial, I firmly understood how the combustion process works in theory and how it can be accurately simulated within ANSYS Fluent. Seeing the end-to-end process including chemistry and physics of combustion, flow pathways, temperature contours, and the behavior and distribution of species was incredibly insightful.

Reginald Langworth –
Is the Species model appropriate for all types of combustion simulations, or does it have certain limitations in ANSYS Fluent?
MR CFD Support –
The Species model is particularly suited for simulations involving separate fuel and oxidizer streams, such as in non-premixed or partially premixed combustion scenarios. Though widely used, it may have limitations for premixed combustion cases or scenarios where detailed chemistry or pollutant formation need to be analyzed.
