有效导热系数及其应用

The Efficient Thermal Conductivities and Its Application

本文以各向同性、均匀介质、导热系数为常数的材料内的导热规律为依据,分别就导热系数为温度的函数、双层复合材料,各向异性材料等情形,推导了有效导热系数的数学表达式,并说明了它们的应用条件。

A efficient thermal conductivity concept has been developedin several problems involving thermal conductivity varying with temperature, two-layer complex plate and anisotropic material. According to a principle in which the heat flux of these plates must be equal to that of a homogeneous isolropic constant thermal conductivity plate, the expression of these efficient thermal conductivities have derived and their applied conditions are also pointed out.
