ABSTRACT: The present theoretical study represents a proposal aimed at
investigating about the possibility of generalizing the canonical
entropy-exergy relationship and the reservoir concept. The method adopted
assumes the equality of pressure and chemical potential as necessary conditions
of mutual stable equilibrium between a system and a reservoir in addition to
the equality of temperature that constitutes the basis for defining entropy as
deriving from energy and exergy concepts. An attempt is made to define
mechanical and chemical entropy as an additional and additive component of
generalized entropy formulated from generalized exergy property. The
implications in exergy method and the possible engineering applications of this
approach are outlined as future developments among the domains involved.
