“…This serves to cool the nanoliquid regime. Similar observations have been reported by Zohra et al and Mehmood et al A more homogenous temperature distribution is computed at both walls at any value of thermal slip parameter, as compared with the profiles associated with the variation in the lower wall thermal Biot number described earlier. Figure C presents the evolution in nanoliquid temperature with a modification in Brinkman number, that is,

“…Radiative heat transfer in nanofluid flows has been examined for peristaltic pumping systems by Prakash et al, who also considered magnetic properties and viscosity variation. Mehmood et al used a modified Buongiorno model to analyze nonorthogonal stagnation flows of nanoliquid solar cell coatings with high thermal radiative flux, thermal jump, and viscosity variation. Kuharat and Bég conducted computational fluid dynamic simulations of annular solar collectors doped with metallic nanofluids (titanium oxide/copper oxide‐water) using STS and P1 radiative flux models and ANSYS finite volume software.…”

A mathematical study is described to examine the concurrent influence of thermal radiation and thermal wall slip on the dissipative magnetohydrodynamic electro‐osmotic peristaltic propulsion of a viscous nanoliquid in an asymmetric microchannel under the action of an axial electric field and transverse magnetic field. Convective boundary conditions are incorporated in the model and the case of forced convection is studied, that is, thermal and species (nanoparticle volume fraction) buoyancy forces neglected. The heat source and sink effects are also included and the diffusion flux approximation is employed for radiative heat transfer. The transport model comprises the continuity, momentum, energy, nanoparticle volume fraction, and electric potential equations with appropriate boundary conditions. These are simplified by negating the inertial forces and invoking the Debye–Hückel linearization. The resulting governing equations are reduced into a system of nondimensional simultaneous ordinary differential equations, which are solved analytically. Numerical evaluation is conducted with symbolic software (MATLAB). The impact of different control parameters (Hartmann number, electro‐osmosis parameter, slip parameter, Helmholtz–Smoluchowski velocity, Biot numbers, Brinkman number, thermal radiation, and Prandtl number) on the heat, mass, and momentum characteristics (velocity, temperature, Nusselt number, etc) are presented graphically. Increasing Brinkman number is found to elevate temperature magnitudes. For positive Helmholtz–Smoluchowski velocity (reverse axial electrical field) temperature is strongly reduced, whereas for negative Helmholtz–Smoluchowski velocity (aligned axial electrical field), it is significantly elevated. With increasing thermal slip, nanoparticle volume fraction is also increased. Heat source elevates temperatures, whereas heat sink depresses them, across the microchannel span. Conversely, heat sink elevates nanoparticle volume fraction, whereas heat source decreases it. Increasing Hartmann (magnetic) parameter and Prandtl number enhance the nanoparticle volume fraction. Furthermore, with increasing radiation parameter, the Nusselt number is reduced at the extremities of the microchannel, whereas it is elevated at intermediate distances. The results reported provide a good insight into biomimetic energy systems exploiting electromagnetics and nanotechnology, and, furthermore, they furnish a useful benchmark for experimental and more advanced computational multiphysics simulations.

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.

“…Zayed et al [16] addressed flat plate solar collector nanofluid performance considering a variety of metal, metal oxides, semiconductor crystalized oxides, and carbon based nanofluids as the absorbing media and noting that copper oxide achieves the best efficiency whereas carbon based nanofluids achieved both superior energy and exergy efficiencies. Mehmood et al [17] investigated the manufacturing flows of solar copper oxide-doped nano-polymer coatings for photo-voltaic applications, noting their superiority in durability, anti-corrosion and thermal efficiency. Dugaria et al [18] studied computationally the thermal performance of aqueous nanofluids containing suspensions of single wall carbon nano-horns (SWCNHs) as volumetric absorbing media in a concentrating direct absorption parabolic trough solar collector.…”
