The Modified Lennard-Jones and Devonshire Equation of State

Blog Article

Lennard-Jones-Devonshire equation of state is an old but theoretical based EOS.The concept of the nearest neighboring molecules or coordination number is proposed to be a function of temperature and volume, whereas it is a constant in the original.The dilute gas Collections and hard sphere Right Foot Pad limits of molecules are employed to determine this function.

Improvement of this modification is demonstrated by property calculations for Lennard-Jones fluid.Results of the modified LJD equation of state offer senior accord with simulation data of Lennard-Jones fluid than those of the original version.
