摘要: We introduce a density-functional formalism based on the Parsons-Lee and generalized van der Waals theories in order to describe thermodynamics of anisotropic particle systems with steric interactions. For ellipsoids revolution, orientational distribution function is obtained by minimizing free energy functional equations state are determined. The system exhibits nematic-isotropic discontinuous transition, characterized phase separation between nematic isotropic phases at finite as well low packing fractions. model presents behavior which good agreement Monte Carlo simulations for aspect ratios.
