Effects of CuO/water nanofluid on the efficiency of a flat-plate solar collector

Progress of nanofluid application in solar collectors: A review

“…According to Moghadam et al [124], the enhanced efficiency of the flat-plate solar collector that was observed with CuO/H 2 O nanofluid was 16.7% for 3 kg/min at 0.4% volume concentration and particle dimension 40 nm. Otanicar et al [125] studied the effect of nanofluids in DASCs and concluded that by varying materials, size, shape and volume fraction, optimization of spectral absorption can be achieved.…”

Experimental test of an innovative high concentration nanofluid solar collector

“…In this work a volume fraction of 3.0% of nanoparticles has been chosen to evaluate the possible problems related to sedimentation and to collect data about the most stressing conditions for the system. Other works used lower nanoparticle concentrations [22][23][24][25] to avoid inevitable sedimentation problems and to reduce pumping problems. In this …”

“…An enhancement between 2.6% and 7.0% was obtained. Moghadam et al [25] studied the effect of CuO-water base nanofluid at 0.4 vol% and average diameter of 40 nm on the efficiency of a flat plate solar collector. An enhancement of 4.74% and 21.8% compared to that of water has been obtained with a mass flow rate of 2 and 1 kg/min respectively.…”

Use of nano-droplet-enriched cutting fluid (NDCF) in ultra-precision machining

“…The term nanofluid is often used to refer to a fluid containing nanoparticles, with sizes between 1 and 1000 nm. It has become increasingly popular to apply nanofluid to cool the workpiece in the course of machining, because of its superior ability to remove heat by forced convection [1]. Effective cooling can suppress adhesion and prevent rewelding of the chip.…”
