The effect of using different Nano fluids on heat transfers through flat plate solar collector

Abstract EN

In this paper investigation experimentally the effect of CuO-water and Al2O3/water nanofluids on heat transfer in flat plate solar collector.

The volume fraction was used (0.125,0.25 and 0.5) % for flow flow rate of working fluid equal to (1 L/min) and the particles size was 20 nm.

The experiments are conducted in Kerbala, Iraq with the latitude of 32.60 N.

The result shows that the maximum outlet-inlet temperatures difference obtained at (0.5 vol.

%) nanofluid are (16.2 0C) for (Al2O3/water), (15.5 0C) for (CuO/water) nanofluid, and (10.2 0C) for pure water.

Also, Al2O3 shows high heat transfer compared to CuO, this lead to improve the performance of the solar fat-plate collector.
