摘要

一个简单而流行的布里奇曼公式预测了热导系数与致密液体声速之间的线性关系。遗憾的是，该公式无法应用于强耦合等离子体相关流体，因为声速会随着屏蔽的减弱而大大增加。我们建议对布里奇曼公式进行修改，将导热系数与横向（剪切）声速相关联。实验证明，这种方法可以合理地

Modified Bridgman Formula for the Thermal Conductivity of Complex (Dusty) Plasma Fluids

A simple and popular Bridgman’s formula predicts a linear correlation between the thermal conductivity coefficient and the sound velocity of dense liquids. Unfortunately, it cannot be applied to strongly coupled plasma-related fluids with screened Coulomb interactions, because the sound velocity can greatly increase as screening weakens. We propose a modification of the Bridgman formula by correlating the thermal conductivity coefficient with the transverse (shear) sound velocity. This approach is demonstrated to work reasonably well in screened Coulomb (Yukawa) fluids and can be useful in the context of complex (dusty) plasmas.
