“…Anbuchezhian et al [46] theoretically investigated the MHD convective flow and heat transfer of an incompressible viscous nanofluid past a porous vertical stretching sheet in the presence of variable stream condition due to solar radiation (incident radiation). The absorbed radiation acted as a distributed source which initiates buoyancy-driven flow and convection in the absorbed layer.…”

This paper presents a detailed review of the numerical studies carried out by various researchers in order to obtain enhanced heat transfer in free, forced, and mixed convection, under laminar, transition, and turbulent flow regimes, by using nanofluids in different solar collector geometries. Recently, nanofluids have been increasingly used in various solar collector configurations. Nano-sized metallic or non-metallic particles such as Cu, Au, Al2O3, SiO2, TiO2, CuO, etc, were used in the heat transfer fluid for various solid volume fractions. The average size of the particles was less than 100 nm. The higher conductivity of nanoparticles even at low particle concentration results in higher thermal conductivity of the base fluid and improves the thermal characteristics of the system. Nanoparticle size, type and shape are important factors for the thermal conductivity enhancement of the nanofluid with nanoparticles.

“…The permeability parameter K is varied from 0.05 to 0.5 (see Refs. 28,31,48). We have chosen here n = 10, nt = π/2, ε = 0.02, and Pr = 6.2 while M, R, S, φ, Q, F, and K are varied over a range, which are listed in the figure legends.…”

“…They found that the effects of the radiation conduction parameter and the surface temperature parameter are significantly stronger on the local Nusselt number than that of the local Sherwood number. The effects of thermal radiation were also investigated by many researchers . Alsaedi et al analyzed the stagnation point flow of a nanofluid near a permeable stretched surface with a convective boundary condition and heat generation.…”

This article studies the effect of thermal radiation on a MHD free convection flow of a nanofluid bounded by a semi‐infinite vertical plate with a constant heat source in a rotating frame of reference. The plate is assumed to oscillate in time with constant frequency so that the solutions of the boundary layer are the same oscillatory type. The dimensionless governing equations for this investigation are solved analytically using the regular perturbation method. The effect of various important parameters entering into the problem on velocity and temperature fields within the boundary layer are discussed for three different water‐based nanofluids such as Cu, Al2O3, and TiO2 with the help of graphs. The predicted results clearly indicate that the presence of nanoparticles in the base fluid enhances the heat transfer process significantly. The present work shows the need for immediate attention in next‐generation solar film collectors, heat‐exchanger technology, material processing exploiting vertical surface, geothermal energy storage, and all those processes which are greatly exaggerated by heat‐enhancement concepts. © 2013 Wiley Periodicals, Inc.

“…Anbuchezhian et al [18] analyzed the case of nanofluids in laminar flows for solar applications. Anbuchezhian et al [19] studied the MHD convective filed and thermal transport of an incompressible-model and viscous-type nanofluid through a porous media by using theoretical techniques. Using BBD (Box-Behnken-design) code, Ghorbanian et al [20] physically optimized a corrugated-surface and porous-type cavity by nanofluid flows in the solar-radiation case.…”

Curves of pressure, lines of current, speed of fluid, fields and diagrams of kinetic energy, and plots of viscosity through a H2O/Al2O3 nanofluid-heat exchanger with recirculation promoters are studied by using a computational approach and a two-dimensional algorithm. The simulation used four nanofluid fractions, i.e. ϕ = 0.5, 1, 2 and 4 percent, with four flow rates, i.e. Re = 5, 10, 15 and 20 (× 103). Both the discontinuous-type deflectors and the detached-model bars are considered to reinforce the nanofluid field structure. The discontinuous-situation of these deflectors allows reducing the pressure on its front-corner by passing the fluid between their internal surfaces. In addition, the field is detached from the front-sharp-edge, forcing the creation of recycling-rings on their back-areas. While, the presence of the detached-bar model in both the top and the lower stations of the exchanger allows an improvement in the flow disturbance across the gaps through their interior-surfaces, and the formation of new recycling-cells near their right-sides. These vortices constitute opposite-currents where their strength increases with increasing nanofluid concentration and Reynolds values.
