Novel approach to the equation of state for fluid systems, based on the concept of the exclusion factor

The review summarises the achievements in the theory of the equation of state. Novel approaches and new high-precision equations of state for one- and multicomponent fluid systems are consdidered. The results are given for both bulk phases and surface monolayers including two-dimensional equations. In the framework of the theory based on the exclusion factor, a hierarchy of approximations is formulated, incorporating both well-established and relatively new equations of state.
