Au nanofluids with enhanced thermal properties for use in CSP.
Abstract Aiming for the introduction of stability requirements in nanofluids processing, an interface-based three-step method is proposed this work. It theory-based design framework that aims a minimum tension at solid-liquid interface by adjusting polar and dispersive components base fluid to meet those disperse nanomaterial. The was successfully tested preparation aqueous containing single-walled carbon nanotubes resulted be stable provide good thermal properties, i.e. conductivity...
Nanofluids are systems with several interesting heat transfer applications, but it can be a challenge to obtain highly stable suspensions. One way overcome this is create the appropriate conditions disperse nanomaterial in fluid. However, when fluid used non-polar organic oil, there complications due low polarity of solvent. Therefore, study introduces method synthesize TiO2 nanoparticles inside typically applications. Nanoparticles produced were characterized for their structural and...
Transition metal dichalcogenides (TMCs) exhibit unique properties that make them of interest for catalysis, sensing or energy storage applications. However, few studies have been performed into nanofluids based on TMCs heat transfer In this study, 2D-WS2 are prepared by liquid phase exfoliation to analyze their potential usage in concentrating solar power plants. Periodic-Density Functional Theory (DFT) calculations were rationalize the success process. The hydrogen bond interaction between...
Abstract Photodegradation processes are of great interest in a range applications, one which is the photodecomposition pollutants. For this reason, analysing nanoparticles that improve efficiency these under solar radiation very necessary. Thus, study, TiO2 was doped with Mo and Cu using low-temperature hydrolysis as method synthesis. Pure x%MoS2/Cu/TiO2 were prepared, where x theoretical quantity MoS2 added (0.0%, 1.0%, 5.5%, 10.0%), setting nominal at 0.5 wt.%. The samples obtained...
This study shows an analysis of the stability nanofluids based on a eutectic mixture diphenyl oxide and biphenyl, which is used as heat transfer fluid (HTF) in concentrating solar energy, NiO nanoparticles. Two surfactants are to analyse nanofluids: benzalkonium chloride (BAC) 1-octadecanethiol (ODT). From experimental perspective, analysed by means UV/Vis spectroscopy, particle size measurements through dynamic light-scattering technique, ζ-potential measurements. The results show that...
A molecular dynamics study based on gold nanofluids performed with and without the presence of tetraoctylammonium halide as a surfactant in base fluid is presented. The consisting mixture biphenyl diphenyl oxide used concentrating solar power (CSP) plants. radial distribution functions (RDFs) spatial (SDFs) were analysed temperature. Theoretical results indicate that acts kind net around nanoparticle plays an active role enhancing thermal properties nanofluid system. greater lability...
In this work, nanofluids were prepared using commercial Cu nanoparticles and a high temperature-heat transfer Fluid (eutectic mixture of diphenyl oxide biphenyl) as the base fluid, which is used in concentrating solar power (CSP) plants. Different properties such density, viscosity, heat capacity thermal conductivity characterized. Nanofluids showed enhanced efficiency. detail, incorporation led to an increase up 14%. Also, was increased 13%. Finally, performance 11% according Dittus-Boelter...
This article reports the preparation and characterization of nanofluids based on heat transfer fluid (HTF) commonly used in concentrating solar power (CSP) plants. Nanofluids were prepared with commercial Ag nanoparticles synthesized Au which dispersed into a base composed by eutectic mixture two stable compounds: diphenyl oxide biphenyl. Both sets characterized attending to its physical chemical stability possible improvement thermal properties respect fluid. Moreover, theoretical analysis...
Nanofluids are colloidal suspensions of nanomaterials in a fluid which exhibit enhanced thermophysical properties compared to conventional fluids. The addition can increase the thermal conductivity, isobaric-specific heat, diffusivity, and convective heat transfer coefficient original fluid. For this reason, nanofluids have been studied over last decades many fields such as biomedicine, industrial cooling, nuclear reactors, also solar applications. In paper, we report preparation...
