摘要: The present work focuses on the numerical simulation of diffusive flames in a confined high-swirl burner. Navier–Stokes equations expressed for time-dependent, compressible, and three-dimensional flow with finite-rate kinetics are solved lean methane/air mixtures. A simplified mechanism is used to model combustion. Non-reactive reactive cases contrasted swirl number 0.95. Three numbers 0, 0.6, 0.95 analyzed. In swirling flows, inner recirculation zone mainly composed reaction products, which help ignition incoming fuel. Moreover, forward stagnation point plays an important role, leading azimuthal deflection flame front.
