Evaluating Shear Viscosity Of Expanded Sodium- Thermodynamic States Dependence
This study is devoted to investigate the shear viscosity of evaporated sodium in four thermodynamic states. To achieve this purpose, first there have been calculated three non-vanishing sum rules for the shear stress auto-correlation function for evaporated Na at four thermodynamics states with the Ashcroft pseudo-potential and the corresponding pair distribution function having been investigated by molecular dynamics simulation. To obtain the shear viscosity, the Mori memory function formalism is introduced. It is found out that by decreasing the temperature, the shear viscosity will be increased. Our results are in good agreement with those of other methods available.
