Thermal Conductivity of Nanofluids
Nanofluids are suspensions of nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. Nanofluids have unique features different from conventional solid-liquid mixtures in which mm or μm sized particles of metals and non-metals are dispersed. Due to their excellent characteristics, nanofluids find wide applications in enhancing heat transfer. Research work ...
متن کاملNanofluids for thermal transport
challenges facing many diverse industries, including microelectronics, transportation, solid-state lighting, and manufacturing. Technological developments such as microelectronic devices with smaller (sub-100 nm) features and faster (multi-gigahertz) operating speeds, higher-power engines, and brighter optical devices are driving increased thermal loads, requiring advances in cooling. The conve...
متن کاملSonication Effects on Stability and Thermal Properties of Silica- Paraflu Based Nanofluids
Cooling is one of the most important challenges in industries, especially in the automotive industry. The coolant which is used in engine radiators possesses lower thermal conductivity. To enhance the thermal properties, coolant was dispersed in nano-sized particles and the fluid is called as Nanofluid. In this Study, Silica Nanoparticle was dispersed in Paraflu Engine coolant usin...
متن کاملPreparation of CuO/Water Nanofluids Using Polyvinylpyrolidone and a Survey on Its Stability and Thermal Conductivity
In this article CuO/water nanofluid was synthesized by using polyvinylpyrolidone (PVP) as the dispersant. Thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. To study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different pH values and PVP surfactant concentrations; also thermal conductivity...
متن کاملAn Investigation on Stability, Electrical and Thermal Characteristics of Transformer Insulting Oil Nanofluids
Transformer insulating oil nanofluid is made to improve dielectric and thermal properties of the oil by employing nanoparticles with proper properties. In the current work, nanofluids based on transformer mineral oil were prepared by three procedures using diamond nanoparticles with high thermal conductivity, as well as high dielectric properties. It was tried to consider the impacts of surfact...
