Cylindrical diffusion laminar flames

Abstract

Axisymmetric tubulaÍ laminar flames are inveitisated in a near equilibrium diffusion .""n"í"0 regime with a thin reaction zone separating tfr" n.f unã oxidizer radial streams The solution ;i thit "normal Burke-schumann like problem" vields the flame position and the concentratlon 'oroÀi"t rot ttt" fuel and oxidizer and' as expected' ii. oroo.t stretching variable for future iiu.rtlgàtion of the flarne strucrure for large u.,iuu,í-energies The temperature profile is also ãúi"i""o f"t ihe classical conditions of Lewis Nurnbers equal to unitY. bsaduÉian The imponance of flame-flow interaclion in Combusiion Research is undeniable 'Jy'hile Premixed flames have been intensively studied. in a wide spectrum of geometries and conditions'' this is not sà with diffusive flames. FoÌlowing the work of Burke and Schumann? who set forth the theory of diffusional combustion and the work of Shvab and Zel'dovichs, who established the general properties of diffusion flames, most of the work has been .""..",t".0 in the counter-flow diffusion flamese'ro ' Senior Research9r, Combustion and
