超临界 CO2 体系黏度分子动力学研究
Molecular Dynamics Simulation of Viscosity in Supercritical CO2
摘要
Abstract
Supercritical CO2 was the most commonly used supercritical fluid due to its low critical empera-ture and moderate critical pressure.It has found wide applications in various fields, such as supercritical fluid extraction, cooling system, and rapid expansion of supercritical solution, etc.Enriching the basic physic data of supercritical CO2 is of positive significance.Equilibrium molecular dynamics simulations were carried out in this study to investigate the viscosity of supercritical CO2 .The numeration process was conducted by our compiled script, based on the Lammps simulator, which was a classical molecular dy-namics code.The calculation outcome were compared with the mature property database.The results showed that the error was less than 0.5% between the calculation and that of the database.And it was feasible to use the presented method to obtain the supercritical CO2 viscosity.关键词
