Propagation, dynamics and control of laminar premixed flames

摘要: Abstract Current state of knowledge laminar premixed flame propagation, dynamics and control is reviewed. A distinction made between planar multi-dimensional flames. Based on the well-established theory propagation free adiabatic flames, different mechanisms to mainly based heat transfer processes in porous media, but also using electrical gravitational fields, are considered. Flame instabilities, leading pulsations or oscillations, for instance an acoustic field, simple physical model interaction a burner presented explain main instabilities burner-stabilized Knowledge flames models describe behavior these mature, although it expected that more sophisticated methods will be used future research their behavior. Multi-dimensional well understood, less mature. Models with flow distortions, stretch curvature derived. The influence such distortions burning velocity terms Markstein number studied. Weak-stretch available multiple species chemistry transport effects especially rich stoichiometric mixtures. Some ways extend improve current indicated. (Bunsen-type) as waves, Experimentally observed phenomena can modeled satisfactory detailed numerical models. However, this area, clear analytical descriptions mature because origin some still largely unknown. Extensions (mostly G-equation like) account flame–flow interaction, flame–flame flame–burner needed. To conclude: set measures adapt combustion system interest at hand by transfer, waves other often like electric fields available. This needed modify practical devices guarantee safe proper operation.
