美国Clayton P. ken报导了许多不缔合工业液体导热系数的计算式。用它计算比用其他方法计算正确得多,更好,更重要。像密度,临界温度,临界压力,沸点,分子量等参量,在外来资料中容易得到。它适合于极性、非极性液体的计算,但不能用于如水、酒精、有机酸等缔合液体的计算。对于球形不缔合液体(极性或非极性)的无量纲导热系数λ,是无量纲温度T、 Clayton P. Ken, USA, has reported many formulas that do not relate to the thermal conductivity of industrial fluids. It is much more accurate, better, and more important to use than it is calculated by other methods. Like the density, critical temperature, critical pressure, boiling point, molecular weight and other parameters, easily available in foreign data. It is suitable for the calculation of polar, non-polar liquids, but not for the calculation of associative liquids such as water, alcohol, organic acids, etc. The dimensionless thermal conductivity λ for a spherical, non-associative liquid (polar or nonpolar) is the dimensionless temperature T,
