between exergy and Second Law efficiencies is not clearly recognized by many. It is attempted here to clarify the definitions … and use of energy and exergy based performance criteria, and of the Second Law efficiency, with an aim at the advancement …

mass flow rate. Increases in wind speed reduce both energy and exergy efficiency of the overall system. …

This paper presents a steady-state and transient theoretical exergy analysis of a solar still, focused on the exergy … temperatures are used to compute energy and exergy flows. Results in the steady-state regime show that the irreversibilities … produced in the collector account for the largest exergy destruction, up to 615W/m2 for a 935W/m2 solar exergy input, whereas …

of the case study analysis for the proposed ORC system indicate a cycle efficiency of 0.05, exergy efficiency of 0 ….17, and energy and exergy cogeneration efficiency of 0.87, and 0.35, respectively. …

simulation incorporating the second law of thermodynamics to evaluate the energy and exergy distribution of various processes in … exergy was destructed during combustion processes, and as EGR level increased to 45% (intake temperature and equivalence … ratio also increased), the combustion destructed exergy decreased to 20% of the fuel exergy. This was largely due to the …
