Numerical Study of Opposed-Jet H_2/Air Diffusion Flame-Vortex Interactions

摘要

We consider the interaction of vortices of different size and strength (vorticity) and a diffusion flame of N_2-diluted H_2 and air stabilized on an opposed-jet burner. In our direct numerical simulations, which take into account the effects of detailed chemistry and transport, we demonstrate the effects of flame curvature of opposite orientations by placing a vortex on either the air or the fuel side of the diffusion flame.
