Title	Numerical Study in the Preheat Zone of Turbulent Premixed Flamelet
Creator	Ma, Hsiao-Kang; Law, Jiu-Yeong
Publisher	Digitized by J. Willard Marriott Library, University of Utah
Date	1995
Spatial Coverage	presented at Monterey, California
Abstract	The governing equations for heat conduction, convection and radiation in a turbulent premixed flamelet can be developed and solved for radiative transfer characteristics of absorbing, emitting and scattering properties. The preheat zone of turbulent premixed flamelet is assumed a non-gray optical and participating medium. The analytical solutions for the above equations by changing parameters of conduction(N1), convection(N2). the optical thickness(to) and the single scattering albedo(coo), …etc. are studied in detail. The participating medium in preheat zone could be regarded as gas and soot mediums. The total emissivity, absorption coefficients in gas medium are calculated based upon wide band models due to the radiative properties vary so rapidly across the spectrum. The Drude-Loreatz dispersed model is used to study the complex refractive iDdex (m = n - ik) of soot which have to be known in solved the total emissivity, absorption coefficients of soot medium.
