“…metal or none-metal oxide powders) dispersed in traditional coolants such as water, ethylene glycol or oil. Such fluids can be a promising way for improving the heat transfer rate and heat dissipation in heat exchanging media [2][3][4][5][6][7][8][9]. Boiling and two-phase flow phenomena are widely used in different industrial applications such as refrigeration, air-conditioning, heat pumping systems, cooling of high-power electronics components and bio-engineering reactors.…”

“…And there is a maximum Nu H,avg at φ=15° for Ra=10 6 , at φ=30° for Ra=10 4 and φ=45° for Ra=10 3 . But there is the obvious maximum for Ra=10 6 , while there is not obvious for Ra=10 5 and Ra=10 4 , and even the Nu H,avg is almost horizontal for Ra=10 4 . This is mainly because heat transfers in the cavity through the natural convection and the inclined angle has influence on the fluid flow in the cavity when the Ra number is higher, while heat transfers in the cavity through the heat conduction and the inclined angle has little influence on heat transfer when the Ra number is lower.…”

Abstract-The paper presents a numerical study of natural convective heat transfer of copper-water in an inclined square cavity where the temperature of one sidewall sinusoidal oscillates, the opposite sidewall is cooled at a relatively low temperature and the other walls keep adiabatic. The transport equations are solved numerically with the finite volume approach using SIMPLEC algorithm. The influence of pertinent parameters such as the inclined angle (-75°～ 75°), the solid volume fraction of copper nanoparticles (0～0.2) and the Rayleigh number (104～106) on the convective heat transfer characters are studies. The results show that the heat transfer rate increases with the increase of the solid volume fraction and the Rayleigh number. And the percentage increase in the time-averaged Nusselt number is 37.61%, when the solid volume fraction is increased from ϕ =0 to ϕ =0.2 at Ra=106. The positive inclined angle is more conducive to heat transfer enhancement than the negative inclined angle, especially for the higher Ra number. And there is the best inclined angle for a given Ra number, and this angle is 15°at the Ra=106.

“…When nanoparticles strategically deployed in the base fluids, the ensuing nanofluids have been verified to achieve remarkable enhancement in the properties of thermal conductivity, as introduced by Choi [8]. This has made nanofluids attractive in various areas of recent technology incorporating heat exchangers [15], aerospace cooling systems [20], and energy systems [17]. The two most common approaches to investigate the phenomena of heat and mass transfer characteristics are either the Tiwari and Das model [26] (which only requires momentum and energy equations and incorporates nanoparticle effects via a volume fraction parameter only) and the Buongiorno non-homogeneous model [6] (which introduces a separate equation for the nanoparticle concentration).…”

This paper deals with the numerical simulation of transient magnetohydrodynamics natural convective boundary layer flow of a nanofluid over an inclined plate. In the modeling of nanofluids, dynamic effects including the Brownian motion and thermophoresis are taken into account. Numerical solutions have been computed via the Galerkin-finite element method. The effects of angle of inclination, buoyancy-ratio parameter, Brownian motion, thermophoresis and magnetic field are taken into account and controlled by nondimensional parameters. To compute the rate of convergence and error of the computed numerical solution, the double mesh principle is used. Similarity solutions are calculated and presented graphically for non-dimensional velocity, temperature, local rate of heat and mass transfer with pertinent parameters. The modified Nusselt number decreases with increasing inclination angle, buoyancy-ratio parameter, Brownian motion and thermophoresis parameter, whereas it increases with increasing Prandtl number. Validation of the results is achieved with earlier results for forced convective flow and non-magnetic studies. Such problems have several applications in engineering and petroleum industries such as electroplating, chemical processing of heavy metals and solar water heaters. External magnetic fields play an important role in electrical power generation, inclination/acceleration sensors, fine-tuning of the final materials to industrial specification because of their controlling behaviour on the flow characteristics of nanofluids.
