Thermodynamic Analysis Of Diesel Engine Fuelled With Aqueous Nanofluid Blends
Published 2019 · Materials Science
Thermodynamic analyses are performed on diesel engine with different types of nanofluid blend operations. Three best blends, i.e., D + 50ZN, D + 50AN, D + 50CN are chosen for exergy analysis. The effects of nanofluid on diesel are examined from the second law perspective. Availability equations are applied to both diesel and nanofluid blend modes at varying engine loads, and exergy terms such as brake work availability, exhaust gas availability, cooling water availability, and irreversibility are calculated and compared. There is an increase in exergy efficiency with an increase in load for all fuel blends tested. The nanofluid blend operations are favored thermodynamically at all loads. For diesel at full load, 26.88% of the fuel exergy is converted to brake power. At same load, nanofluid blend modes have resulted higher exergy efficiency of 28.22, 28.78, 29.16% for D + 50ZN, D + 50AN, D + 50CN, respectively, due to the higher brake work availability and decreased destruction availability.
