Simulation Modeling of an Enhanced Low-Emission Swirl-Cascade Burner

[摘要] The numerical computations were conducted using the CFD-CHEMKIN computational program. A cell-centered control volume approach was used, in which the discretized equations or the finite difference equations (FDE) were formulated by evaluating and integrating fluxes across the faces of control volumes in order to satisfy the continuity, momentum, energy and mixture fractions conservation equations. The first order upwind scheme and the well-known SIMPLEC algorithm were used. The standard k-{var_epsilon} model was used to close the set of equations. The thermal and composition fields in the baseline, cascade, swirl, and swirl-cascade burners were simulated. The temperature and CO{sub 2} concentration fields were just computed and the observations are reported. The analysis of these results is currently underway.
