The Effective Coefficients of Thermal Conduction in Absorptive Disperse Media : No.1 Steady State Case

The effective coefficients of transport phenomena in disperse media are estimated conveniently by utilizing the so-called cell model method. This method, however, loses its capability in cases where the media are absorptive. A cell model method is proposed in the present paper which is capable of dealing with the case of absorptive disperse media. This method is derived by approximating the actual fine temperature field by a smoothed-out field as closely as possible on the basis of a certain estimate function. The proposed method will be effective in more complicated cases such as spray combustion.
