Abstract Using nanofluids as an innovative kind of liquid blend including trivial volume fraction (in percent) of millimeter or nanometer size powdered particles with base fluids is fairly a novel arena or idea. The objective of this presented review paper is to inspect the performance of the nanofluid-based solar collector (NBSC).

Nanofluids are the fluid that has shown various developments in the thermal properties over the past decade. In the field of nanotechnology, nano fluids have a great potential to enhance the rheological properties like thermal conductivity of base fluid like water, ethanol etc. Nanofluids are the suspension of mainly the base fluid like water in nanoparticles such as alumina (Al2O3) of size micro or milimetre and shows distinctive features than that of conservative fluids used. Because of better rheological properties nanofluids are utilized to build up the performance of conventional solar thermal engineering systems.

Increasing Thermal Conductivity of a Heat Exchanger Using Copper Oxide Nano F...IJERA Editor
A Nano fluid is the evolving concept which is very rarely used in the many core industries. Nano fluids have
found a great application in heat exchangers by increasing the thermal conductivity. We have aimed to
increasing the heat transfer co-efficient by using copper oxide Nano fluid. The Nano particles are formed by
using precipitation method and their fluids are formed by adding surfactants to the base fluid. The comparative
study on the Heat exchanger is made by using the CuO Nano Fluid and Hot water. The analysis and the results
shows that the overall heat transfer rate increases when subjected to Nano Fluids. The ethylene glycol fluid used
along with copper oxide Nano fluid will offer resistance to fouling.
CFD Analysis for Heat Transfer Enhancement Using Nano Fluids in Double Pipe H...ijtsrd
This work includes the effect of different working fluid on the performance of heat exchanger. For analysing the effect of different working fluid, it considered air, water and different nanofluids and measure the Nusselt number and friction factor for each case. It also analysed the effect of change in Reynolds number on the performance of heat exchanger for different working fluids. For analysing the effect of change in Reynolds number, it considered four different Reynolds numbers that is 10000, 12000, 14000 and 16000. For performing the numerical analysis ANSYS fluent was used. Through numerical analysis it is found that for air as a working fluid heat transfer is less, whereas in case of water it is marginally higher than the air. But for all nano fluids, heat transfer is much higher than the air and water. For analysing the effect of different nano fluid, this work includes three nano fluids that are Al2O3, TiO2and ZrO2. Through analysis it is concluded that heat transfer is more in case of TiO2 as compared to other nanofluids, air and water. With increase in Re number heat transfer gets increase whereas as friction factor get decrease.

Effect of nanofluid on friction factor of pipe and pipe fittings part ii ef...eSAT Journals
Abstract A nanofluid is prepared by mixing nano sized particles of size up to 100 nm and a base fluid. Commonly used nanoparticles are made of metals, oxides or carbides, while base fluids may be water, ethylene glycol or oil. Normally, the application of nanofluids is to enhance the heat transfer rate. Due to mixing of nanoparticles in the base fluid, the thermo-physical properties of the resulting mixture (base fluid + nanoparticles) changes. Therefore, resistance to flow of nanofluid increases which increases the friction factor and reduces the flow rate. In the part I of paper, an experimental investigation has been carried out to determine the effect of various concentration of Al2O3 nano-dispersion mixed in water as base fluid on Friction Factor of Pipe and Pipe Fittings. The present study deals with the effect of CuO nanofluid on the Friction Factor of Pipe and Pipe Fittings. The friction factor and loss coefficient of different pipes and pipe fittings increase with increase in volume concentration of CuO in water as compared to water. Keywords: Nanofluid, Friction Factor, Pipe Friction, Pipe Fitting, CuO Nanoparticles
Computational Analysis of CuO Nano Coolant in a Car RadiatorIOSRJMCE
Nanofluids are basically nanoparticles in base fluids. Nanofluids have unique features different from conventional solid-liquid mixtures in which nano sized particles of metals and nonmetals are dispersed. Due to improvement of mechanical properties, nanofluids are widely used in heat transfer industries. The coolant is used water-based, with the addition of glycols to prevent freezing and other additives to limit corrosion, erosion and cavitations. In this study 50-50 mixture of Ethylene Glycol with water (EGW) is tested and compared with another mixture by adding 2 percent Copper oxide (CuO). The geometric model of radiator is uploaded in Autodesk CFD software for its computational analysis. It is analyzed up to 100 iterations. Both the results are compared to find the improved heat transfer rate due to the addition of 2% CuO with Ethylene Glycol and water
