Description

In this project, a combustion chamber with DPM has been simulated, and the simulation results have been investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The 3-D geometry of the present model is carried out using SpaceClaim software.

The meshing of this present model has been generated by Ansys Meshing software. This mesh uses tetrahedral elements, which are then converted into a polyhedral mesh using Fluent software.

Also, due to the nature of the present problem, the transient solver has been enabled.

Combustion Methodology

In this project, we simulated the gas turbine combustion chamber using a discrete phase model (DPM) and species transport model by Ansys Fluent software.

In this case, the effect of spraying Benzene combusting particles is done using the Eddy- dissipation combustion and the volumetric sub-models. This combustion chamber is commonly used for jet engine users. Also, the species transport model is enabled to model the combustion process.

Both the airflow and fuel enter through their respective inlet boundaries with a velocity of 3m/s. Moreover, the SST k-omega model and energy equation are used to solve the turbulent fluid equations and calculate temperature change within the domain.

Combustion Conclusion

After the simulation, we obtain the contours related to temperature, chemical species mass fraction, and particle tracks. First, benzene fuel reaches the nozzle in the form of sprayed particles, and then I transfer it to the combustion chamber with great speed.

Combustion occurs inside the nozzle and enters the combustion chamber at high speed and temperature. According to the animation, the flame moves slowly while the fuel penetrates faster.
