“…Xun et al 19 thrashed out the involvement of dependent viscosity in bioconvection of nanoparticles in a rotating system. Mosayebidorcheh et al 20 operated a modified least square technique in order to examine the bioconvection utilization in nanoparticles configured in a horizontal channel. Sk et al 21 examined the various slip trends in nanofluid flow under the impulsion of gyrotactic microorganisms.…”

Recent progress in nanotechnology and nanoscience has attended the researchers' interest due to its inspiring industrial and technological applications. This contribution investigates the bioconvection flow of Carreau fluid over a periodically moving stretched surface with important feature of magnetic field and thermal radiation. Bioconvection in non-Newtonian nanofluid is utilized with sustaining the joint features of buoyancy and magnetic forces. In addition, thermal radiation consequences are summarized in the energy equation while further computations have been operated under ''one parametric approach.'' The attended problem is contested with a famous convergent technique having excellent accuracy. A comprehensive graphical approach is constituted to describe the thermo-physical features of interesting physical parameters. The reported results may use in enhancement of extrusion system, bio-fuels, and biotechnology.

“…The nanofluid is represented by the model that includes both the effects of Brownian motion and thermophoresis. Mosayebidorcheh et al [12] analyzed the bioconvection nanofluid flow which contains both nanoparticles and gyrotactic microorganisms. They investigated a flow in a horizontal channel considering the model proposed by Kuznestov and Nield [13].…”

in which the nanofluid particle volume at the wall is passively rather than actively controlled. Here, we observed that the boundary conditions are not satisfied in all curves of the nanoparticle volume fraction, , i. e. the curves do not match the boundary conditions presented in eq. (19). The second note is that all values of  are positive which contradicts with the results presented in [15]. Since the equations are coupled then it can be said that not only the behaviors of  are wrong but also all the results presented in that paper is not correct. The main reason for conducting this investigation is performing a revision for the mentioned paper and presenting a set of curves to show the corrected behaviors for dependent variables.

“…It is taken for granted that stability of resulting nanofluid suspension is maintained and it is dilute (nanoparticles concentration less than 1%) to uphold the gyrotactic microorganisms bioconvection in optimum manner. Since high viscosity of base fluid pose negative influence on bioconvection, it is imperative to dilute the suspension containing nanoparticles (Kuznetsov, 2012;Mosayebidorcheh et al, 2017). Following the approach given by Mutuku and Makinde (2014) we used the above mentioned boundary layer approximations i.e.…”

MHD biconvective flow of Powell Eyring nanofluid over stretched surface

The present work is focused on behavioral characteristics of gyrotactic microorganisms to describe their role in heat and mass transfer in the presence of magnetohydrodynamic (MHD) forces in Powell-Eyring nanofluids. Implications concerning stretching sheet with respect to velocity, temperature, nanoparticle concentration and motile microorganism density were explored to highlight influential parameters. Aim of utilizing microorganisms was primarily to stabilize the nanoparticle suspension due to bioconvection generated by the combined effects of buoyancy forces and magnetic field. Influence of Newtonian heating was also analyzed by taking into account thermophoretic mechanism and Brownian motion effects to insinuate series solutions mediated by homotopy analysis method (HAM). Mathematical model captured the boundary layer regime that explicitly involved contemporary non linear partial differential equations converted into the ordinary differential equations. To depict nanofluid flow characteristics, pertinent parameters namely bioconvection Lewis number Lb, traditional Lewis number Le, bioconvection Péclet number Pe, buoyancy ratio parameter Nr, bioconvection Rayleigh number Rb, thermophoresis parameter Nt, Hartmann number M, Grashof number Gr, and Eckert number Ec were computed and analyzed. Results revealed evidence of hydromagnetic bioconvection for microorganism which was represented by graphs and tables. Our findings further show a significant effect of Newtonian heating over a stretching plate by examining the coefficient values of skin friction, local Nusselt number and the local density number. Comparison was made between Newtonian fluid and Powell-Eyring fluid on velocity field and temperature field. Results are compared of with contemporary studies and our findings are found in excellent agreement with these studies.
