摘要:
本文就第一、三类边界条件求解了偏心情况下空心球体导热微分方程。获得了球体内温度分布并给出热阻的表示式。分别计算了测定导热系数时因偏心造成的误差。分析了南工Ⅰ型装置的偏心误差,并指出最大误差不超过1%。
Abstract:
In this paper the differential equations of steady heat conduction through an eccentric hollow spheroid with first and third kinds of boundary conditions are solved. The temperature distributions in the spheroid is obtaind and the equivalent thermal resistance is also given. The error of measurement of heat conductivity caused by eccentricity is estimated. An analysis of the heat conductivity test-apparatus type NK-I shows that the error does not exceed 1% with an extreme value of eccentricity of 10%.
