主　　题：conjugate radiation conduction transient annealing process 

摘      要：The annealing time is an important affecting factor in the performance of many *** present work deals with the transient simulation of annealing process in a cubic furnace in which a solid element is placed in its *** the working gas can have some radiating features,a set of governing equations including the energy balance with the radiative transfer equation(RTE)for the gray radiating medium and the conduction equation inside the solid product are numerically solved with progressing in *** results which are validated against both analytical and theoretical findings in the literature demonstrate that during the starting period,a high rate of radiant energy transfers into the solid body even at small optical *** behavior which hastens the rate of heat transfer at low values of the radiation conduction parameter,causes a fast annealing process in which the solid body warms up to its maximum ***,it is revealed that the rate of heat transfer is an increasing function of radiation-conduction parameter.
