Aghamiri Department of chemical engineering, Isfahan university, Isfahan, Iran H. Modarress Amirkabir university of technology, Tehran, Iran G.A. Mansoori University of Illinois at Chicago, Chicago, USA Journal Article 2016 05 29 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 and hard sphere 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. <em> </em>   https://www.ijche.com/article_15183_cd14d7eac0e4638dca6ef495702dd013.pdf
