Engineered Nanofluids for Heat Transfer and Novel Applications

Timofeeva E.V., Singh D., Yu W., France D., Argonne National Laboratory, US

Nanofluids are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow for engineering the multifunctional [...]

Nanofluidics: Wetting and Spreading Phenomena and Applications

Wasan D., Nikolov A., Illinois Institute of Technology, US

Suspensions of nanometer-sized particles in liquids (nanofluids) are used in a variety of technological applications and biological systems. For example, their spreading and adhesion behavior on solid surfaces can yield materials with desirable structural and [...]

Possible explanations of the deviations in the thermal conductivity measurements

Han K., Lee M., Koo J., Kedzierski M.A., Kyung Hee University, KR

Nanofluids were invented to enhance thermal conductivity of the working fluid near the wall region, where the conduction is the only mechanism to dissipate heat and it limits the heat transfer rate from a body [...]

Alignment of Different Functional Single Wall Carbon Nanotubes using Fe2O3 Nanoparticles under External Magnetic Field

Younes H., Hong H., South Dakota School of Mines and Technology, US

In this work we describe a new approach to align functionalized single walled carbon nanotubes (SWNTs) by γ-Fe2O3 in the presence of an external magnetic field without using chemical surfactant. Five different functionalized SWNTs are [...]

Experimental investigation on solidification behavior of water based CNT nanofluids for cool thermal storage system

Kumaresan V., Anna University, IN

Nano-enhanced phase change material (NEPCM) was prepared by two step method using distilled water as the base fluid, sodium dodecyl benzene sulphonate (SDBS) as a surfactant, pseudomonas as nucleating agent and multi-walled carbon nanotubes (MWCNT) [...]

Modeling Thermophoresis (Soret Effect) in Nanofluids

Eslamian M., Ziad Saghir M., Texas A&M Univeristy- Corpus Christi, US

Thermophoresis plays an important role in forced and natural convection in channels and enclosures when nanofluids are used instead of pure fluids. Therefore, in order to be able to estimate the extent and role of [...]

Thermal Performance of Silver/Water Nanofluids in Heat Exchangers

Bandarra Filho E.P., Oliveira G.A., Federal University of Uberlandia, BR

Nanofluids are fluid formed by dispersing solid particles of size ranging 1-100 nm (nanoparticles) in a given base fluid such as water or oil, for example. Regarding to the thermal potential, the researches on nanofluids [...]

Ultrasound absorption in magnetic nanofluids

Sokolov V.V., Nadvoretskiy V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Mechanisms of ultrasound absorption in magnetic nanofluids at the absence of external magnetic field are theoretically studied in the first part of the paper. The novel magnetodynamic mechanism of ultrasound absorption is introduced – it [...]

Nanocarbon Nanofluids: Comparisons Between Morphology and Nanostructure

Vander Wal R.L., The Pennsylvania State University, US

Reported here are experimental results of studies designed to identify the operable mechanisms responsible for the gains in thermal conductivity of nanoﬂuids based on nanocarbons. Comparison of functionalized versus nonfunctionalized nanocarbons addresses the effect of [...]

Effective Viscosity of the nanofluids: Experimental studying and molecular dynamics simulation

Rudyak V.Ya., Dimov S.V., Krasnolutsky S.L., Ivanov D.A., Novosibirsk State University of Architecture & Civil Engineering, RU

The studying the effective viscosity coefficient of the nanofluids is the object of present paper. Experimentally the viscosity of the nanofluids on basis of ethylene glycol and SiO2 nanoparticles was studied. It was shown that [...]
