Interaction of a Planar Laminar Premixed Flame with a Perpendicular Wall 800285

We study, herein, the steady, isobaric two-dimensional interaction with a flat perpendicular wall of an otherwise planar fuel-lean hydrocarbon-air premixed laminar flame, stabilized on a heat-sink burner. We report isotherms, and isoconcentration contours for hydrocarbons, in the quench layer on a cold isothermal side wall from results of numerical (ADI) integration of the elliptical boundary-value problem for a one-step irreversible Arrhenius-type chemical reaction. Also, burning near a single hot or adiabatic wall, and reduction of flame speed in a parallel-plate crevice-type duct with cold walls, are discussed.
