摘要
采用分子动力学模拟方法研究了液体氩与固体界面的相互作用性质 ,得到了一定温度下氩的饱和压力参数与固壁尺度的关系。数值计算结果表明 ,微尺度下液体的饱和性质存在尺度效应。固体壁面尺度越小 ,液体氩的饱和压力越低 ;当固体壁面尺度增加时 ,液体氩的饱和压力也随之增加 ;固体壁面尺度超过一定值后 。
The character of interaction between surface of solid wall and liquid argon at saturated state was studied by molecular dynamics simulation. The relation of saturation pressure of liquid argon with size of solid wall was obtained under fixed temperature. Numerical calculation indicates that there exists a size effect under micro scale for the saturation pressure of liquid argon. The smaller is the size of the solid wall, the lower is the saturation pressure of liquid argon. The value of saturation pressure of liquid argon will increase with the increase of size of solid wall until it reaches the saturation pressure of liquid argon in bulk volume when the size of the solid wall exceeds a certain limit.
