“…In recent year, several researchers studied the nanofluid boundary layer flow with various physical effects in the occurrence of magnetic field. (Hamad, 2011;Malvandi et al,2014;Noreen et al, 2015). Further, Sandeep (2016) and Ramana Reddy et al (2017) considered the heat transfer behaviour of MHD flows.…”

The effect of chemical reaction on MHD free convection heat transfer flow of a nanofluid bounded a semi-infinite flat surface in a rotating frame of reference is theoretically investigated. The velocity along the plate (slip velocity) is assumed to oscillate on time with constant frequency. The analytical solutions of different water based nanofluids containing TiO2, Al2O3, Ag, Cu and CuO of the boundary layers are assumed, to keep the problem as realistic as possible. The dimensionless governing equations for this investigation are solved analytically by using the small perturbation Technique. The effects of various physical parameters on velocity, temperature and concentration fields are presented graphically. The enhancement in magnetic parameter leads to a considerable reduction in velocity and chemical reaction parameter is predominant in controlling the concentration profile. The results obtained in the simulation of perturbation method are in well agreement with realistic situation of the scientific scenario.

“…He also proposed a correlation for the determination of the thermal conductivity of alumina nanofluids based on the experimental data. Though several attempts have been made on nanofluids to explain the physical reasons for the heat transfer enhancement [13,14], there are still many conspicuous inconsistencies and the investigators are working on, see for example some recent attempts in [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”

Radiation and heat generation effects in unsteady magnetohydrodynamic mixed convection flow of nanofluids along a vertical channel are investigated. Silver nanoparticles of spherical shapes and of different sizes in water as a convectional base fluid are incorporated. The purpose of this study is to measure the effect of different sizes of nanoparticles on velocity and temperature. Keeping in mind the size, particle material, shape, clustering and Brownian motion of nanoparticles, Koo and Kleinstreuer model is used. The problem is modeled in terms of partial differential equations with physical boundary conditions. Analytical solutions are obtained for velocity and temperature, plotted and discussed. It is concluded that increasing the size of Ag nanoparticles (up to specific size, 30 nm, results in a very small velocity increment while for large particle size (30-100 nm), no change in velocity is observed. As the small size of nanoparticles has the highest thermal conductivity and viscosity. This change in velocity with size of nanoparticles is found only in water-based nanofluids with low volume fraction 0.01 while at low volume concentration, no change is observed.

“…He studied that the peristaltic flow for the long wavelength and low Reynolds number. Many researchers and scientists diverted their research interest towards the study of peristaltic transport by considering viscous and non-viscous fluids with different models and with different geometries, few references are given in the reference list [3][4][5][6][7]. Recent developments on the theoretical and experimental mechanism of peristaltic flow are given in the references [8][9][10].…”

The present paper deals with the behavior of gyrotactic microorganisms in nanofluid affected by the magnetic field and porous medium. The advantage of adding motile microorganism is to stabilize the nanoparticle suspension generated by the combined effects of buoyancy force and magnetic field. Gyrotactic microorganisms enhanced the heat transfer, mass transfer and improve the stability of the nanofluids. The mathematical model includes the equations of conservation of mass, momentum, energy, nanoparticle concentration and microorganism equations. The governing equations have been fabricated for long wavelength and low Reynolds number approximations. The solutions have been evaluated for pressure gradient, nanoparticle concentration, temperature and motile microorganism equations are solved by using a powerful technique known as the homotopy analysis method. Effects of physical parameters like a fluid parameter, Brownian motion parameter, thermophoresis parameter, bioconvection Peclet number, Hartmann number and Grashof number are considered. Obtained results are displayed in graphs. The results reveal that bioconvection decreases the pressure gradient because convection instability takes place within the system that causes convection pattern which decreases the pressure gradient. Such result helps in biomedical sciences and engineering. Since, microorganisms are favorable in the decomposition of organic material, producing oxygen and maintaining human health.
