An equation of state has been developed for convex nonspherical particles with nonpolar and multipolar forces. The effects of nonsphericity and multipolarity on phase behavior are characterized by a geometric shape parameter and an energy fluctuation parameter, respectively. The equation performs for real fluids better than the Van der Waals equation and as well as the Redlich‐Kwong and Peng‐Robinson equations.
