Thermal and mechanical aspect of entropy-exergy relationship [PDF]

International Journal of Energy and Environmental Engineering, 2012
The mechanical aspect of entropy-exergy relationship, together with the thermal aspect usually considered, leads to a formulation of physical exergy based on both useful work and useful heat that are the outcomes of available energy of a thermodynamic system with respect to a reservoir.
