Available Energy and Exergy

摘要: An "available energy" is defined for every state of any system. The definition independent (a) the concept work. (b) reference environment, and (c) makeup system (e.g. "macro" or "micro). On basis this available energy, given composite system, contribution each subsystem to energy -- that is, exergy content a defined, as well instantaneous "dead state" subsystem. Some pedagogical, scientific engineering implications are discussed.
