... temperature, and outer surface temperature of the furnace are inversely proportional to exergy efficiency. Based on the static exergy analysis results, measures to improve the exergy efficiency of the heating furnace are proposed: controlling the excess air coefficient within a reasonable range, reducing...

.... The maximum productivity of the conventional solar still was found to be 3.25 L/m 2 /day. On the other hand, the results reveal improvement in productivity of 17.54%, 48.61%, and 55.69% with cases II, III, and IV, respectively. Although stills with energy storage units exhibited higher exergy efficiency...

..., refrigeration load, exergy of refrigeration, and energy and exergy efficiencies of the cooling-power cogeneration cycle. Results show that the elevated pressure of turbocharger results in the enhancement of HCCI engine power and increase of the refrigeration of thermal load, simultaneously. However...

...L. Syam Sundar; Kotturu V.V. Chandra Mouli; Zafar Said; Antonio C. M. Sousa Experiments were conducted to evaluate the thermal entropy generation, frictional entropy generation, and exergy efficiency of reduced graphene oxide (rGO)–Fe 3 O 4 –TiO 2 hybrid nanofluid flow in a circular tube under...

... by ∼2.64% and ∼6.62% for nearly the same collector output temperature attainable (≈98.5°C), while the energy and exergy efficiencies decreased significantly by ∼24.6% and ∼38.6%, compared with ten tubes arrangement. Daily yield and overall exergy efficiency are increased by 13.3% and 19.3%, respectively...
