Description |
The thermal-diffusive model was applied to demonstrate possibility of formation of oscillating or rotating spatial flame structures, which were described previously in experimental works on premixed gas combustion in the clearance between two disks with radial feeding of premixture. The gas flow was assigned and described by the Poiseuille-flow velocity profile. Rotating and oscillating flame patterns in a radial channel were observed only within certain ranges of gas flow rates. Formation of these special flame structures is related to preheating of unburned mixture by hot walls and non-uniform velocity distribution inside the microchannel. (C) 2012 The Combustion Institute.
