... analysis of tubular heating furnaces from the perspective of energy quality. First, an exergy balance model and exergy analysis evaluation criteria are established for the energy system of the heating furnace. Then, the internal and external exergy losses in the heating furnace's energy system...

... in the downhole environment was investigated from both theoretical analysis and numerical calculations. Then the energy analysis and exergy analysis of the refrigeration cycle are carried out in detail. The study considers three refrigerants: octane, nonane, and cyclohexane. Finally, the heat transfer...

... validated by the experimental and numerical studies performed previously. Moreover, the exergy analysis has also been conducted for the convergent dual intake vortex tube for various convergent angles, cold mass fraction, and intake pressure. The study concludes that the convergent vortex tube having a dual...

... and potential energies for each stream are neglected. Chemical exergy is neglected except in the combustion chamber. The exergy-based investigation of any thermal energy conversion system is a more advanced way of analysis and improvement than the first law-based analysis. Exergy analysis reveals...

... the exhaust in the early stage and the sweeping gas in the late stage separately. GT-Power software and Flowmaster software are used to co-simulate and design the exhaust energy splitting system. Through exergy analysis of the exhaust piping system before and after the energy splitting, the exergy efficiency...
