计算有机二元混合液导热系数的一种方法

A Method or Calculating Thermal Conductivity for Binary Organic Mixed Solutions

本文在Ｗｏｈｌ型方程之上，结合Ｃｈａｐｍａｎ导热理论和Ｅｇｒｉｎｇ的反应速率理论，导出了一个二元液体混合物导热系数关联式，该关联式对于非理想程度中等、特别是接近理想的二元体系精度较高．计算了１４种二元混合液体导热系数，与文献值相比最大误差为３．２％。

According to the Wohl equation, and combined the Chapman heat conduction and the Eyring reaction rate theory, an equation for the thermal conductivity of binary mixed solution is derived, which has good accuracy for binary system at close idal state. The thermal conductivities for 14 binary mixed solutions are calculated, a good agreement is fund between the value calculated and value referenced, and the maximun error is about 3. 2%.
