Rapid Determination of Materials Thermal Conductivity by Transient Timing Method

利用一维非稳态导热积分方程.提出了测定材料导热系数的瞬态计时法.与稳态及准稳态法相比,显著提高了测试速度与测试精度.并以有机玻璃和电木为例进行了实际测定.

This paper presents transient timing method which is used to determine materials thermal conductivity by using the integral equation of one-dimensional transient conduction.Compared with steady-state method and quasi-steady-state method,this method quickens measurement and increases relative accuracy greatly.We made experiments with organic glass and bakelite.It is found that this method can be used to determine materials thermal conductivity effectively.
