论文摘要
Lennard-Jones流体的传输特性的冻结密度缩放是根据Rosenfeld的多余熵缩放和Roskilde-Simple Systems的同构理论而合理化的。然后，证明冰点密度缩放在液体氩，k和Xenon的粘度和热导率系数方面合理地运作。讨论了在最小值和冰冻条件下降低的运输系数的准通行性。冰点处的热导率系数的大小显示与密集流体中传热振动模型的预测非常吻合。
A freezing density scaling of transport properties of the Lennard-Jones fluid is rationalized in terms of the Rosenfeld's excess entropy scaling and isomorph theory of Roskilde-simple systems. Then, it is demonstrated that the freezing density scaling operates reasonably well for viscosity and thermal conductivity coefficients of liquid argon, krypton, and xenon. Quasi-universality of the reduced transport coefficients at their minima and at freezing conditions is discussed. The magnitude of the thermal conductivity coefficient at the freezing point is shown to agree remarkably well with the prediction of the vibrational model of heat transfer in dense fluids.
