Nanofluids are used as coolants in heat transport devices like exchangers, radiators, and electronic cooling systems (like a flat plate) because of their improved thermal properties. The preeminent perspective this study is to highlight the influence combined convection on transfer pseudoplastic non-Newtonian nanofluid flow towards an extendable Riga surface. Buongiorno model incorporated prese...

This paper scrutinizes the nonlinear multibubble model with considering bubble-bubble (BB) interaction in Cu−Al2O3/water hybrid nanofluid over vapour bubble radius Newtonian mediums. Firstly, we present derivation of extended Rayleigh-Plesset (ERP) equation under effect BB nanofluids based on Navier-Stokes equation. The is formulated by continuity equation, ERP and relations thermophysical feat...

BACKGROUND AND OBJECTIVES Bacterial resistance to conventional antibiotics has become a widespread public health problem. The aim of this study was to investigate the influence of zinc oxide nanoparticles (ZnO NPs) on the antibacterial activity of several conventional antibiotics against Pseudomonas aeruginosa. MATERIALS AND METHODS ZnO NPs were prepared by solvothermal method and dispersed i...

This article reports a recent study on the application of a two-phase closed thermosyphon (TPCT) in a thermosyphon for economizer (TPEC). The TPEC had three sections of equal size; the evaporator, the adiabatic section, and the condenser, of 250 mm × 250 mm × 250 mm (W × L × H). The TPCT was a steel tube of 12.7-mm ID. The filling ratios chosen to study were 30, 50, and 80% with respect to the ...

This article considered the steady two-dimensional boundary layer flow of incompressible viscous Casson nanofluids over a permeable, convectively heated, shrinking/stretching slippery sheet surface. The achievements this work are extremely relevant, both theoretically with respect to mathematical modeling non-Newtonian nanofluid heat transfer in engineering systems and cooling applications. com...

In this study, the steady forced convection flow and heat transfer due to an impermeable stretching surface in a porous medium saturated with a nanofluid are investigated numerically. The Brinkman-Forchheimer model is used for the momentum equations (porous medium), whereas, Bongiorno's model is used for the nanofluid. Uniform temperature and nanofluid volume fraction are assumed at the surface...

Pool boiling heat transfer characteristics of Al2O3 -water nanofluids is studied experimentally using a NiCr test wire of 36 standard wire guage diameter. The experimental work mainly concentrated on (1) change of critical heat flux with different volume concentrations of nanofluid and (2) flow visualization of pool boiling using a fixed concentration of nanofluid at different heat flux values....

In this Letter, dynamic wetting of water nano-droplets containing non-surfactant gold nanoparticles on a gold substrate is examined via molecular dynamics simulations. The results show that the addition of non-surfactant nanoparticles hinders the nano-second droplet wetting process, attributed to the increases in both surface tension of the nanofluid and friction between nanofluid and substrate...

Several materials, such as aluminum and copper, exhibit non-Newtonian rheological behaviors. Aluminum copper nanoparticles are ideal for wiring power grids, including overhead transmission lines local distribution lines, because they provide a better conductivity-to-weight ratio than bulk copper; also some of the most common materials used in electrical applications. Therefore, current investig...
