3-D Simulation of Methane/air Combustion in the Ring Porous Medium Burner

摘要

The different mathematical and physical models of one-dimension or two-dimension for premixed air combustion in the ring porous medium burner are reported in the literatures. In this paper, a case of combustion of methane/air ratio 0.6, the fluid velocity 0.2m/s and the adiabatic wall of burner is simulated by three-dimensional single temperature model. The numerical results show a good agreement with two-dimensional model for combustion characteristics, such as temperature and velocity distributions in burner, which provides important theoretical basis for the development of new porous medium burners.
