“…Heat transfer performance of a nano uid inside an enclosure pool was examined by Khanafer et al [22]. There exist extensive studies on nano uids of viscous and non-Newtonian uids [23][24][25][26][27][28][29][30][31][32][33]. Recently, Akram and Nadeem [34] discussed the e ects of nano uid and partial slip on the peristaltic transport of a Je rey uid model in an asymmetric channel.…”

Abstract. This paper deals with the e ect of nano uid and inclined magnetic eld on peristaltic transport of a fourth grade uid model. Mathematical modelling of two dimensional fourth grade uid along with nano uid model are given for channel. Assumptions of long wave length are employed to simplify the governing equations of momentum, temperature, and nano particle volume fraction. The exact solutions of temperature and nano particle volume fraction are calculated. Analytical solution is carried out to calculate the solution of stream function. Pressure rise and pressure gradient on the channel walls have been computed numerically. The graphical results are discussed to see the e ects of various emerging parameters on di erent wave forms.

“…Several other applications considered the flow of nonNewtonian nanofluids in the presence of magnetohydrodynamics, radiation and porous media to derive analytic solutions to describe them. This has a great importance for several industrial applications we are currently using but have not yet streamlined and fully understood or are future candidates for nanofluid applications, for example, the flow of liquid metals, cosmic plasmas, MHD pumps and power generators, electrostatic precipitation processes, the petroleum industry, purification of crude oil and several others [13,14,[16][17][18][19][20][21]. Finally, the research community also started to include studies on the natural and forced convection of nanofluids in porous media which is currently a rare novelty in the field [22][23][24].…”

Nanofluids are two-phase mixtures consisting of small percentages of nanoparticles (sub 1-10 %vol) inside a carrier fluid. The typical size of nanoparticles is less than 100 nm. These fluids have been exhibiting experimentally a significant increase of thermal performance compared to the corresponding carrier fluids, which cannot be explained using the classical thermodynamic theory. This study deciphers the thermal heat transfer mechanism for the conductive heat transfer mode via a molecular dynamics simulation code. The current findings are the first of their kind and conflict with the proposed theories for heat transfer propagation through micron-sized slurries and pure matter. The authors provide evidence of a complex new type of heat transfer mechanism, which explains the observed abnormal heat transfer augmentation. The new mechanism appears to unite a number of popular speculations for the thermal heat transfer mechanism employed by nanofluids as predicted by the majority of the researchers of the field into a single one. The constituents of the increased diffusivity of the nanoparticle can be attributed to mismatching of the local temperature profiles between parts of the surface of the solid and the fluid resulting in increased local thermophoretic effects. These effects affect the region surrounding the solid manifesting interfacial layer phenomena (Kapitza resistance). In this region, the activity of the fluid and the interactions between the fluid and the nanoparticle are elevated. Isotropic increased nanoparticle mobility is manifested as enhanced Brownian motion and diffusion effects

In the present study, we examined the effect of induced magnetic field for the peristaltic flow of four different nanoparticles with the base fluid water in the presence of Brownian motion, in a vertical asymmetric channel. The mathematical formulation is presented. Exact solutions have been evaluated for the resulting equations. The obtained expressions for velocity, temperature, pressure gradient and magnetic force function are described through graphs for various pertinent parameters. The streamlines are drawn for some physical quantities to discuss the trapping phenomenon.
