C104 NONGRAY ANALYSIS OF 2-DIMENSIONAL RADIATIVE HEAT TRANSFER INCORPORATING THE INFLUENCE OF NARROW BAND NONUNIFORMITY(Radiation)

概要

論文の詳細を見る
Nongray analyses of radiative heat transfer in a 2-dimensional furnace of practical scale were carried out taking the narrow band nonuniformity of absorption coefficient into account. The results obtained from such numerical simulation were compared with those obtained from nongray analyses where the narrow band nonuniformity of absorption coefficient was neglected. Numerical simulations of radiative heat transfer were coupled with a numerical prediction of flow and combustion process in some cases and conducted based on the given distributions of temperature and species concentrations in other cases. These comparisons showed that disregard of narrow band nonuniformity led to an overestimation of wall heat flux due to radiative heat transfer when the distributions of temperature and species concentrations were fixed without linkage to radiative heat transfer.
