“…They also proved that the value of local Nusselt number enhanced with the addition of the nanoparticles volume fraction and consequently, improved the convective heat transfer from surface to the fluid. The recent investigations on the application of nanofluids were analyzed by Alamri et al (2019), Amirsom et al (2019), Aziz et al (2018), Hassan et al (2019), Khashi'ie et al (2019), Mohamed et al (2016), Sheikholeslami et al (2019), Sohail et al (2019), and Zaimi et al (2017). However, there are also a few of literatures that highlighted the significance and application of non-Newtonian nanofluid in the fluid dynamics.…”

The present study accentuates the Marangoni convection flow and heat transfer characteristics of a hybrid Cu-Al 2 O 3 / water nanofluid past a stretching/shrinking sheet. The presence of surface tension due to an imposed temperature gradient at the wall surface induces the thermal Marangoni convection. A suitable transformation is employed to convert the boundary layer flow and energy equations into a nonlinear set of ordinary (similarity) differential equations. The bvp4c solver in MATLAB software is utilized to solve the transformed system. The change in velocity and temperature, as well as the Nusselt number with the accretion of the dimensionless Marangoni, nanoparticles volume fraction and suction parameters, are discussed and manifested in the graph forms. The presence of two solutions for both stretching and shrinking flow cases are noticeable with the imposition of wall mass suction parameter. The adoption of stability analysis proves that the first solution is the real solution. Meanwhile, the heat transfer rate significantly augments with an upsurge of the Cu volume fraction (shrinking flow case) and Marangoni parameter (stretching flow case). Both Marangoni and Cu volume fraction parameters also can decelerate the boundary layer separation process.

“…Anisotropic slip bioconvection nanofluid flows have been addressed by Raees et al (2016) and Uddin et al (2016). Recently, several nanofluid flows past a surface (movable/non-movable) are inspected under various physical constraints (for fluid flow) (Akbarzadeh et al 2018;Alamri et al 2019;Aziz et al 2018;Hassan et al 2018aHassan et al , 2018bHussain et al 2018;Jamaludin et al 2018;Mahat et al 2018;Rashidi et al 2018;Shehzad et al 2018;Zeeshan et al 2018).…”

A theoretical study is presented for three-dimensional flow of bioconvection nanofluids containing gyrotactic microorganisms over a bi-axial stretching sheet. The effects of anisotropic slip, thermal jump and mass slip are considered in the mathematical model. Suitable similarity transformations are used to reduce the partial differential equation system into a nonlinear ordinary differential system. The transformed nonlinear ordinary differential equations with appropriate transformed boundary conditions are solved numerically with the bvp4c procedure in the symbolic software, MATLAB. The mathematical computations showed that an increase in Brownian motion parameter corresponds to a stronger thermophoretic force which encourages transport of nanoparticles from the hot bi-axial sheet to the quiescent fluid. This increases the nanoparticle volume fraction boundary layer. Fluid temperature and thermal boundary layer thickness are decreased with increasing stretching rate ratio of the bi-axial sheet. The present simulation is of relevance in the fabrication of bio-nanomaterials and thermally-enhanced media for bio-inspired fuel cells.

“…Aziz et al [26] have reported that the boosted up of nanoparticles volume fraction in a nanofluid enhances the heat transfer rate in a thin film flow across an unsteady stretching sheet. Further, [27,28] interviewed the nano-liquid film stream because of a moving substrate and heat transfer by considering seven distinct kinds of nanoparticles.…”

On the account of technological development and engineering applications, the enhancement of thermal energy by introducing nanoparticles is a crucial task in the present era. This present work is to investigate the physical characteristics of a chemical reaction, heat and mass transfer effects on hydrodynamic stagnation point flow of Watlers-B nanoliquid configured by a stretching surface. The effect of fluid viscosity, electrical and thermal conductivity is assumed as temperature function. In addition, the impression of thermal conductivity, Brownian and thermophoretic diffusion are incorporated in the revised model. A theoretical framework is employed to simulate the arisen nonlinear (PDEs).With the assistance of transformations techniques, the contemporary (PDEs) are then diminished to nonlinear system of (ODEs). For nonlinear computations, the resulting equations are programmed in the Mathematica 11.0 programing platform. The impression of the model parameters on diverse flow fields is visualized through plotted graphs. Stability and convergence analysis is established for the authentication of the proposed model. Researchers are encouraged to conduct trials to authenticate the innovative consequences provided in this study, which could be obliging in the improved design of mechanical systems comprising the nanofluids that enables heat and mass transfer mechanism.
