Abstract
This paper presents results of investigations on the application of
CuO-water nanofluids for intensification of convective heat transfer.
Performance of nanofluids with 2.2 and 4.0 vol.% CuO NPs (nanoparticles)
content were examined with regard to heat transfer coefficient and
pressure losses in case of turbulent flow in a tube. Negligible impact of
examined nanofluid on heat transfer improvement was found. Moreover,
measured pressure losses significantly exceeded those determined for
primary base liquid. The observations showed that application of nanofluid
for heat transfer intensification with a relatively high solid load in the
examined flow range is rather controversial.
