Improving The Cooling Performance Of Automobile Radiator With Ethylene Glycol Water Based Zro2 Nanofluid And Compare With Al2o3 Nanofluid Semantic Scholar

Investigated Al 2 O 3 water nanofluid in the car radiator and found 45 heat enhancement than pure waterNguyen et al.

. 39 Heat transfer over flat plate has been analyzed by many researchers. This paper is aimed at understanding thermohydrodynamic and neutronic characteristics of nanofluids for prospective application to water cooled small modular reactors. For the cooling fluid the spherical shape of Al 2 O 3 nanopowders 20 nm is used in this study to prepare five different weight concentrations from 005 to 05 wt of nanofluid samples.

The best obtained value of the overall efficiency is around 9373 for the studied system. Indian and Malaysian scientists have developed a new cooling system featuring an assembled back-channel attached on the rear sides of solar panels to channel flows of titanium oxide and water. 2 P a g e.

It was found that by using SiC-water nanofluid as a coolant instead of water an improvement of approximately 725-1243 could be achieved and by using TiO 2-water 763-1277. For this purpose a single-phase model was considered and the comparison with past researches were carried out in terms of the heat transfer coefficient. Hence the enhancement of their thermal conductivity at room temperature was considered in the majority of the research 8.

Production 1 liter of the most promising nanofluid will then be used to develop and refine a pilot-scale production process 100 liters. This feature is extremely important for ultrahigh-performance cooling systems. They are known to have higher thermal conductivity compared to that of the base fluid.

Due to the fourth industrialization this standalone distilled water in MCHS has its limitation of dissipating a large amount of heat flux from a small area Drummond et al. Carried out experiment Al 2 O 3 water at 68 volume nanoparticle concentration in the radiator type heat exchanger and found 40 increase in heat transfer coefficientHwang et al. Nanofluids are primarily used for their enhanced thermal properties as coolants in heat transfer equipment such as heat exchangers electronic cooling system such as flat plate and radiators.

Al203water nanofluidγ-Al203water nanofluid possess. Similarly the average improvement in the electrical efficiency is observed as 14 and 674 than standalone PV panel and PVT system with water cooling. The maximum temperature rise for water and nanofluid is around 55 and 91C respectively which confirms the better cooling ability of PVT system by nanofluid compared with water.

The specific heat capacity and actual density of alumina nanoparticles used in this study are 780 J kgC and 3690 kgm 3 respectively. Nanofluids implement a conception of improving the thermal properties of liquids by the addition of a solid phase 8. The cooling medium is made of distilled water as a heat transfer carrier.

IOSR Journal of Mechanical and Civil Engineering IOSR-JMCE e-ISSN. Nanofluids which consist of a carrier liquid such as water ethylene glycol dispersed with tiny nano-scale particles known as nanoparticles. Nanofluids are fluids that contain nanoparticles such as metals oxides carbides and nitrides with sizes less than 100 nm.

One such possibility exists in the nanofluids. Nanofluids have expanded enthusiasm for many engineering fields because of its excellent characteristics which can be effectively utilized in electronics cooling and also improve energy effectiveness. On using hybrid nanofluids in the PV panel the thermal efficiency of the system is improved to about 2723 than using water as cooling medium.

Even a small addition of 04 vol CuO nanoparticles enhances the thermal conductivity of water by 8. Milestones This project started in September 2008. Development of candidate water-based nanofluids with optimized compositions particle type size and distribution.

40 However they are also useful for their controlled optical properties. It is observed that even small volumetric concentration of nanoparticle enhances the heat transfer coefficient of base fluids to greater extent. Earlier Water was widely used in radiator as a coolant for its good ability to holding heat transfer.

Apart from being a good performance coolant nanofluid also enhance the energy absorption of material. The researchers throughout a world examine a viability of the nanofluids utilization in various equipment and phenomenon. Cuwater nanofluid and Al 2 O 3-Cuwater hybrid nanofluid.
