We use Monte Carlo and molecular dynamics simulations to study phase behavior and transport properties in a symmetric binary fluid where particles interact via Lennard-Jones potential. Our results for the critical behavior of collective transport properties, with particular emphasis on bulk viscosity, is understood via appropriate application of finite-size scaling technique. It appears that the critical enhancements in these quantities are visible far above the critical point. This result is consistent with an earlier report from computer simulations where, however, the authors do not quantify the critical singularity.
我们使用蒙特卡罗和分子动力学模拟来研究通过 Lennard-Jones 势相互作用的对称二元流体中的相行为和输运性质。我们通过适当应用有限尺寸标度技术来理解集体输运性质的临界行为，特别是对体粘滞系数的研究。这些量的临界增强似乎在临界点以上很远的地方就能看到。这一结果与早期的计算机模拟报告一致，然而，作者没有对临界奇点进行量化。
