In the present work the effect of
working fluid (Al2O3 + water nanofluid) on the efficiency of a parabolic
trough solar collector was investigated
experimentally. The weight fraction of nano particles was 0.1%
and the particles dimension was 40 nm.
Experiments were performed with and without nanofluid. The
mass flow rate of nanofluid is constant
at 2 Lit/min. The results shows that, nanofluid based parabolic
trough collector has higher efficiency
than water based parabolic trough collector. For 0.1%, the
increased solar thermal efficiency was
nearly 7%. From the results, it can be concluded that the
nanofluid causes an enhancement in heat
transfer coefficient by 32%. The paper presents the
preparation of nanofluid, calculation
of nanofluids properties, test result and performance evaluation of
Parabolic Trough Solar Collectors with and without
nanofluids.
