In this project, a combustion chamber is simulated using ANSYS CFX software. We perform this CFD project and investigate it by CFD analysis. The model is a cylindrical combustion chamber.
The fuel which is selected ethane in this simulation, enters the domain from a small circular boundary from the inlet boundary with the velocity value of 60 m/s. Also, the air is inserted inside with a velocity value of 2 m/s and a temperature of 300K.
Eventually, the air and ethane mix inside the chamber and the reaction occurs. Due to the reaction, the new materials are produced as products of the reaction.
The geometry of the simulation is generated inside the SpaceClaim software. Also, the meshing of this project has been done with ANSYS Meshing software. The whole element number is 1,147,748.
Combustion Chamber CFD Simulation Methodology
The reaction of Ethane Air WD1 is defined as solution reactants and the combustion model is Eddy Dissipation.
The Thermal Energy model is selected for heat transfer and the turbulence model is Scalable K-Epsilon.
The Advection Scheme and Turbulence Numerics are set to Upwind and First Order respectively.
At the end of the solution process, two-dimensional contours, vectors, streamlines, and volume rendering related to velocity, pressure, Temperature, and the Mass Fraction of all the components available in the simulation are obtained.
As shown in the figures, the pressure amount inside the chamber is visible, which decreases slowly and uniformly until it reaches a negative value.
The air and ethane enter the domain from the inlet boundary conditions, mix and the reaction occurs so that the temperature of the chamber increases to more than two thousand kelvins.
Additionally, from the velocity contours, vector, and streamlines you can get how the flow exits from outlet boundary conditions in a uniform manner.
Finally, the mass fraction of all components (reactants and products) is shown in different contours.
