abstract: in this study, al 2 o 3 /eg and tio 2 /eg nanofluids as coolants have been used in the double-tube heat exchanger. the hot solvent inlet heat exchanger must be cooled down with a specified amount. we can use nanofluids as coolants in the heat exchanger for optimization of the heat transfer area. therefore, the efficacy of nanofluids as coolants is verified. furthermore, flow rate of c...

The cooling system of an Automobile plays an important role in its performance, consists of two main parts, known as radiator and fan. Improving thermal efficiency of engine leads to increase the engine's performance, decline the fuel consumption and decrease the pollution emissions. Water and ethylene glycol as conventional coolants have been widely used in radiators of an automotive industry ...

Nano fluids are widely used today for various energy-related applications such as coolants, refrigerants, and fuel additives. New coolants design modifications being explored due to renewed interest in improving the working fluid properties of heat exchangers. Several studies have investigated nanofluids enhance radiator exchanger performance. A new class includes single, binary, tertiary nanop...

the term nanofluids was first coined by sir stephen choi in 1995 at argonne national laboratory ,u.s.a .since the discovery, nanofluid have been explored as heat transfer fluids. nanofluids increased the thermal conductivity of existing coolants (water, ethylene glycol) by a magnitude of hundred times which made them attractive for miniaturization of electronic devices .from 1995 till 2008 nano...

This paper contains the results of a concise statistical review analysis of a large amount of publications regarding the anomalous heat transfer modes of nanofluids. The application of nanofluids as coolants is a novel practise with no established physical foundations explaining the observed anomalous heat transfer. As a consequence, traditional methods of performing a literature review may not...

Nanopowders/Nanostructures have attracted the attention of engineers and scientists for their tunable properties extended applications. One application nanopowders is nanofluids. Nanofluids are assumed as most preferred next generation coolants stability essential successful implementation. Iron oxide nanoparticles were prepared by sol-gel method using Ferrous sulphate precursors. The character...
