Description
Summary:The viscosity of liquid Na and Fe was estimated by using a non-equilibrium molecular dynamics simulation. The effective pair potential used for Na, which is based on the pseudopotential method, reproduces excellently the temperature dependence of viscosity in liquid Na. For Fe, an experimentally determined pair potential from the Born-Green equation and effective pair potentials based on the hybridized expression of a nearly free electron tight-binding method were used. These potentials were used to calculate the temperature dependence of viscosities of liquid Fe. The results obtained are fair to good, qualitatively and semiquantitatively. For comparison, g(r)s based on the usual molecular dynamics simulation for these liquid metals were also calculated, and the results were satisfactory.
