Combustion Chamber Steady-State, Ansys Fluent CFD Simulation Training
In this project, a Combustion Chamber Steady-State CFD Simulation using ANSYS Fluent is carried out. We perform this CFD project and investigate it by CFD analysis.
The current model is designed in three dimensions using the SpaceClaim software. The model is a cylindrical combustion chamber.
Four inlet sections for airflow are radially around the combustion chamber, and four inlet sections for fuel flow are axially at the top of the chamber. One outlet section for combustion reaction products is determined at the bottom of the combustion chamber.
The meshing of this project has been done with ANSYS Meshing software. The element number is 2626307.
Combustion Chamber Methodology
The combustion chamber is one of the most widely used devices in the industry. Therefore, experts are working to improve the performance of the combustion chamber. In this project, a combustion chamber is simulated using Ansys Fluent software. The present combustion chamber has two air inlets.
The air of the first inlet hits several blades (to circular the flow) and then enters the chamber; To create a better flame, the air from the second inlet does not enter the combustion chamber at first, instead of entering through the perforations in the combustion chamber. The fuel used in this combustion chamber is methane.
The species transport model has been used to define the chemical reaction between air and methane. This chemical reaction consists of five species, including O2, N2, CH4, CO2, and H2O.
The airflow consists of 0.21 oxygen with a flow rate of 0.005 kg/s and a temperature of 430 K entering the combustion chamber, and the fuel flow enters the combustion chamber with a flow rate of 0.0001kg.s-1 and a temperature of 300 K at the same time.
It is also assumed that the outer wall of the combustion is adiabatic and has a heat flux of 0W/m2. Moreover, the RNG k-epsilon model and energy equation are enabled to solve the turbulent fluid equations and calculate temperature distribution inside the domain.
Combustion Chamber Conclusion
At the end of the solution process, two-dimensional contours related to temperature and velocity are obtained. According to the results, it is observed that good combustion took place in the chamber, and the average temperature of the chamber reached 1006.5k.
