Effects of Second-Order Velocity Slip and the Different Spherical Nanoparticles on Nanofluid Flow

Abstract

The paper theoretically investigates the heat transfer of nanofluids with different nanoparticles inside a parallel-plate channel. Second-order slip condition is adopted due to the microscopic roughness in the microchannels. After proper transformation, nonlinear partial differential systems are converted to ordinary differential equations with unknown constants, and then solved by homotopy analysis method. The residual plot is drawn to verify the convergence of the solution. The semi-analytical expressions between NuB and NBT are acquired. The results show that both first-order slip parameter and second-order slip parameter have positive effects on NuB of the MHD flow. The effect of second-order velocity slip on NuB is obvious, and NuB in the alumina–water nanofluid is higher than that in the titania–water nanofluid. The positive correlation between slip parameters and Ndp is significant for the titania–water nanofluid.

Computational analysis of rotating flow of hybrid nanofluid over a stretching surface

“…Nanofluids are mainly used in heat transfer, and fuel cells, including microelectronics, chillers, pharmaceutical processes, heat exchangers, machining, and boilers for reducing the temperature of flue gases. Heat transfer in nanofluids through the parallel plate network with different nanoparticles was studied by Zhu et al 1 Heat transfer through a heat exchanger with the help of carbon nanofluids was studied by Alasady and Maghrebi. 2 ZnO ethylene glycol/water nanofluid's heat transfer and flow behavior inside mini channels of two multiports were presented by Wen et al 3 The thermophysical properties were studied by adding TiO 2 species with the spherical and wire-like arrangements in water-based nanofluid was experimented by Hosseini and Dehaj.…”
