Analysis of Combustion and Turbulence Models in a Cylindrical Combustion Chamber
The combustion process of methane downstream of an axisymmetric sudden expansion in a circular pipe with a constant wall temperature has been studied. The conservation equations of mass, momentum, energy, and species as well as additional equations due to turbulence modeling have been numerically solved. The standard k − ε model and eddy dissipation combustion model has been used to simulate the turbulence and combustion phenomenon, respectively. The governing equations have been discretized using a finite volume approach and power law scheme and the resulting set of algebraic equations has been solved simultaneously. The numerical results have been compared with the other’s numerical results and experimental data.
