“…Dogonchi et al [17] have discussed the motion of nanofluid within the partially heated rhombus cavity with thermal radiation using control volume finite difference technique. Few more studies can be seen in [18][19][20][21][22][23][24][25] in the direction of liquid flow situation with thermal radiation effect.…”

In this paper, we have investigated the two-dimensional magnetohydrodynamic steady boundary layer flow of a viscous magnetomicropolar liquid via an extending area. The impact of heat sink/source and chemical reaction is considered. The governing equations are modeled in Cartesian coordinate system. Using the suitable similarity transformations, the partial differential equations system is changed into the nonlinear ordinary differential equations system. The resulting system of equations is solved via mathematical renowned software Mathematica. The impact of diverse parameters through microrotation, concentration, temperature and velocity is examined via graphs. The present study reveals that the velocity is rising function of Soret number, Richardson number and Grashof number. It is mentioned that the greater velocity is located in the case of Newtonian liquid in contrast with the micropolar liquid. In the absence of chemical reaction parameter, the velocity is more as compared with higher chemical reaction parameter. Radiation, Hartmann and chemical reaction parameters augment the temperature. Concentration is a reducing function of radiation, Hartmann and chemical reaction parameters.

“…Mondal and Pal [10] used the Mathematica software to analyze the nanofluid flow past a stretching sheet with motile gyrotactic microorganisms, and they were convinced that their results are applicable to bio-nanocoolant systems and bioconvection energy conversion devices. Several recent studies on the topic can be cited in [11][12][13][14][15][16][17].…”

In this study, a novel model of entropy generation effects measured in the Cu-blood flow of a nanofluid under the effect of ciliary-oriented motion is proposed. The effects of viscous dissipation are also taken into account. The physical model was composed with the incorporation of a low Reynolds number and long-wavelength phenomena. The exact solutions for the axial velocity, temperature and pressure gradient distribution were achieved successfully. Key findings are presented through a strategy of plotting the significant factors affecting the physical quantities of the stream. It was found that the heat absorption parameter and Brownian motion accounted for the large thermal transfer rate, while the effect of entropy was minimal compared to these factors in the center of the flow but increased on the walls in the case of Cu-blood flow. It can also be added that a more intense flow gave rise to the entropy effects. This study may be helpful in medical science as cilia play vital roles, which include cell migration and external fluid transport, in human tissues and some key organs. Moreover, the considered annulus-shaped geometry gives vital readings that are used in medical equipment such as endoscopes.

“…Since the paper by Devi and Devi [6] was published, many researchers have studied the hybrid nanofluids past surfaces that are stretched or shrunk, such as Rostami et al [9], Waini et al [10,11], Khashi'ie et al [12], Zainal et al [13], to mention just a few authors. We can also mention the following published papers suggested by reviewers: Rahman et al [14], Shafiq [15][16][17], Sanni et al [18], Khan et al [19], Khan [20] and Makinde [21], Mabood et al [5]. The heat transfer applications of hybrid nanofluids are: industrial cooling applications; smart fluids (due to the lack of abundant sources of clean energy and widespread dissemination of battery operated devices, such as cell phones and laptop it is essential to use nanofluids as a smart fluid; biomedical applications; cancer therapeutics (this initiative involves the use of iron-based nanoparticles as delivery vehicles for drugs or radiation in cancer patients); liquid cooling of computer processors due to their high thermal conductivity.…”

The present paper studies the flow and heat transfer of the hybrid nanofluids flows induced by a permeable power-law stretching/shrinking surface modulated orthogonal surface shear. The governing partial differential equations were converted into non-linear ordinary differential equations by using proper similarity transformations. These equations were then solved applying a numerical technique, namely bvp4c solver in MATLAB. Results of the flow field, temperature distribution, reduced skin friction coefficient and reduced Nusselt number were deduced. It was found that increasing mass flux parameter slows down the velocity and, hence, decreases the temperature. Furthermore, on enlarging the stretching parameter, the velocity and temperature increases and decreases, respectively. In addition, that the radiation parameter can effectively control the thermal boundary layer. Finally, the temperature decreases when the values of the temperature parameter increases. We apply similarity transformation in order to transform the governing model into a system of ODEs (ordinary differential equations). Numerical solutions for particular values of involved parameters are in very good agreement with previous calculations. The most important and interesting result of this paper is that for both the cases of shrinking and stretching sheet flows exhibit dual solutions in some intervals of the shrinking and stretching parameter. In spite of numerous published papers on the flow and heat transfer over a permeable stretching/shrinking surface in nanofluids and hybrid nanofluids, none of the researchers studied the present problem. Therefore, we believe that the results of the present paper are new, and have many industrial applications.
