An Analytical Method of Non-Gray Three-Dimensional Radiation Heat Transfer in Spray Combustion,
Abstract
A computational study of radiation heat transfer in a combustor having fuel spray combustion is reported in the present paper. When the distribution of radiatively participating species is known in either a normal distribution or an exponential distribution in any direction of cylindrical coordinates with respect to a referenced location, e.g., in a form, F = fexp, where f, a, b, and c are distribution constants for individual species, the governing equation of radiation heat transfer without scattering in such a system can be solved with relative ease by using the herein reported method. Several results from the present author's work are explained that are employed for implementing the solution: a new coordinate transformation method to find the species distribution along individual optical paths centered at any chosen location in the combustor; a new formula for the adiabatic flame temperature in a logarithmic function facilitating solutions for various radiation equations; a new inverse error function enabling some exact solution of the governing equation of radiation heat transfer, etc. Keywords: Analytical Solution, 3 D Radiation, Computation, Optically Thin, Optically Thick, Species Distribution, Blackbody Radiation Function, Inverse Error Function, Combustors, Fuels, Fuel spray.
