Abstract:
Publication on cavity flow natural convection by using
nanofluids has increased in recent years. On the other hand,
contrary results offered by different researchers, both in
experimental and numerical works. In this research it is tried to
indicate that the accuracy of the viscosity and the thermal
conductivity of the nanofluids is the most important reason of
the contrary results. Therefore, cavity flow natural convection
of CuO-water nanofluids has considered experimentally for
volume fractions 0.5% and 1% in this research. The results
show that the natural convection of nanofluids are more
sensitive on accuracy of the viscosity than the thermal
conductivity as well as it recommends to measure the viscosity
and thermal conductivity in experimental natural convection
works. However, for the range of the volume fractions tested in
this research, CuO-water nanofluids (30-50nm) have not shown
heat transfer advantage.
