摘　　要：We present an inverse analysis of the conductive and radiative heat transfer problem in fibrous porous materials.The porosity and total heat transmission are simultaneously recovered in the finite-volume method and genetic algorithm scheme for both uniform and nonuniform porosity distributions.We solve the heat transfer equations directly to obtain the total heat transmission that defines the objective function to be minimized in the inverse analysis.The results show that the combined scheme is an effective tool for the inverse analysis of fibrous porous materials.
