A study of Lennard-Jones equivalent analytical relationships for modeling viscosities
The analysis of the viscosity-density-temperature relationship of the Lennard-Jones (LJ) fluid was studied over a wide range of temperature and density. The viscosities of LJ fluids were evaluated through the qualitative trends generated by combining the LJ and equivalent analytical relationships (E...

| Resumo: | The analysis of the viscosity-density-temperature relationship of the Lennard-Jones (LJ) fluid was studied over a wide range of temperature and density. The viscosities of LJ fluids were evaluated through the qualitative trends generated by combining the LJ and equivalent analytical relationships (EAR). It was found that the viscosity predictions were based only on the molecular weight. The average error was less than 10% for vapor and supercritical viscosity and less than 25% for liquid viscosity. |
