dc.description.abstract | Entropy and exergy analysis of a thermal system are the most powerful tools that can be
employed to specify the optimum operating conditions of that system and utilization rate from the
system. In the experimental thermal system in this work, entropy generation and exergy analyzes
of GO–DW nanofluids have been carried out in straight copper pipes with constant heat load and
8mmand 16mminner diameters.While the heat loads applied to the pipes are 250Wand 350W, the
range of fluid flow rate values in the pipes is 0.9 l/min–1.8 l/min. GO–DW nanofluids with 0.01%
and 0.02% volumetric concentrations and DW have been used as working fluids in the pipes. The
outcomes acquired from this work have been matched with the studies using different nanofluids in
the literature and it has been noticed that the outcomes are reasonable and consistent. The results of
the study have been presented at differentGO–DWnanofluid concentrations in pipes with 8mmand
16 mminner diameters as thermal, friction and total entropy production, output exergy ratio and 2nd
law efficiency. The obtained outcomes have exhibited that the lowest total entropy generation has
been obtained for the 8 mm diameter pipe and the nanofluid with 0.02% GO–DW concentration.
Besides, 2nd law efficiency is 12% higher for the 8 mm diameter pipe than 16 mm at flow rate of
1.2 l/min and 0.02% GO–DWnanofluid, and 350Wheat load. | tr |
