Each of the following topics is analyzed and discussed from a logical/philosophical viewpoint to arrive at an appropriate conclusion. • Nomenclature for Exergy. • The Proper Thermodynamic Reference Temperature for Exergy Calculations. • Exergy Calculations for Apparently Adiabatic Processes. • Exergy Destruction. • Exergy Balances. • Fuel-Use Factors for Different Forms of Exergy. • Thermodynamic Inefficiencies Not Detected by Exergy Analysis. The conclusions result in a set of governing “rules” that differ in many respects from views commonly held. Accordingly, they will be controversial. Thus, although it is not expected that these rules will be universally accepted, it is hoped that, at the least, they will stimulate further discussions within the Second Law community.
