Abstract
This paper describes the procedure to calculate the effective thermal conductivity of unidirectionally oriented fiber assemblies. The procedure takes account of not only the heat conduction but also the heat radiation with the use of shape factors described in the previous paper. Numerical computation gave the following conclusions:
(1) The temperature distribution in a fiber assembly is linear if the heat transfer in the assembly takes place only by heat conduction But if the heat radiation works, the distribution becomes nonlinear in the region, where the heat radiation is effective.
(2) The results of the numerical computation for the effective thermal conductivity of a fiber assembly show that the present method can well reproduce the dependence of the effective thermal conductivity on the volumetric ratio of fiber in the assembly.
