用MD方法计算磁场条件下水的粘度

摘要

Molecular dynamics simulations were performed in 256 water molecules under different magnetic fields. The internal energy, viscosity and radial distribution function have been calculated. The research results indicated that the relation between viscosity and magnetization is multi_extremum relation, the effect of magnetization is the most distinct under the condition of B=0.25 T and normal temperature.%将水系统视为正则系综，采用分子动力学模拟（Molecular dynamics simulation 简称MD）方法对磁场作用下水的内能、粘度和径向分布函数进行了计算. 研究结果表明：磁场可以影响g(r)的分布，使水的结构发生变化，从而导致水的粘度发生改变；粘度与外加磁场强度的关系呈多极值特征，且在B=0.25 T以及常温下磁化效果最为明显.
