... the utilization of phase change materials with metal foam. The cooling of the battery is further achieved through convective flow of a nanofluid mixture of Al2O3 in water utilizing various tube arrangements. The implementation of the model is carried out using the finite volume method. The study concerns...

... Abstract The effect of particle sedimentation on the evaporation rate of nanofluid droplets on a heated substrate is studied numerically. A two-dimension model of droplet evaporation and deposition using Arbitrary Lagrangian-Eulerian (ALE) method is developed, considering evaporation cooling...

... 18 10 2010 Turbulent convective heat transfer and pressure drop of •-Al 2 O 3 /water and CuO/Water nanofluid inside a circular tube were experimentally investigated and compared. The nanofluids were very dilute. Results indicated that addition of small amounts of nanoparticles...

... 18 10 2010 Nanofluids are engineered colloidal dispersions of nano-sized particle in common base fluids. Previous pool boiling studies have shown that nanofluids can improve critical heat flux (CHF) up to 200% for pool boiling and up to 50% for subcooled flow boiling due to the boiling...

... 18 10 2010 Nanofluids have attracted increasing interest for more than a decade. A number of studies have demonstrated that nanofluids presented intriguing heat transfer enhancement performances. We produced a series of nanofluids and measured their thermal conductivities. The most...

... 18 10 2010 The term of nanofluid refers to a solid-liquid mixture with a continuous phase which is a nanometer sized nanoparticle dispersed in conventional base fluids. Recent investigations on nanofluids indicate that the suspended nanoparticles markedly change the transport...

... are not common. However, nanofluids can be used in direct solar absorbers to improve their performances. The objective of this paper is to evaluate the potential of application of nanofluids in direct solar absorbers. Spectral transmittances of nanofluids within the solar spectrum have been measured...

... 18 10 2010 In this paper, we assume that a nanofluid is a mixture consisting of a continuous base fluid component and a discontinuous nanoparticle component. Then, based on the analysis of Buongiorno in 2006 for critical slip mechanisms in nanofluids, we consider the effects...

... 18 10 2010 This study shows the transient characteristics of the pool boiling curves using nanofluid as the boiling fluid. This time-dependency is in sharp contrast to a unique steady-state pool boiling curve that is typically obtained for a pure fluid. Past researches on nanofluids...

... 18 10 2010 Nanofluid is a colloidal solution of nano-sized solid particles in liquids. Ar-Al nanofluid is a promising heat transport fluid in the fields of low-temperature engineering. A simplified model based on the equilibrium molecular dynamics (EMD) simulation is constructed...

... significantly. More importantly it was found that the surface wettability and roughness are considerably increased, which could plausibly explain the large CHF enhancement in nanofluids [9]. words: nanofluid, flow boiling, critical heat flux Inspired by the notable outcomes of the pool boiling experiments...

... 23 06 2009 Laminar convective heat transfer and viscous pressure loss were investigated for alumina-water nanofluid in a flow loop with a vertical heated tube. The experimental results are in good agreement with traditional model predictions for laminar flow, if the loading...

... 23 06 2009 Nanofluids have been attractive for the last few years with the enormous potential to improve the efficiency of heat transfer fluids. This work focuses on the effect of pH and sodium dodecylbenzenesulfonate (SDBS) surfactant on the thermal conductivity of nanofluids.The...
