“…Large Brownian motion means the more random motion of fluid particles thus strengthening the concentration of the fluid and an opposing impact is visualized for the thermophoretic parameter on the fluid’s concentration. All these findings are according to the recently published articles 12 , 49 , 50 .…”

The dynamics of partially ionized fluid flow subjected to the magnetic field are altogether distinct in comparison to the flow of natural fluids. Fewer studies are available in the literature discussing the alluring characteristics of the Hall effect and the Ion slip in nanofluid flows. Nevertheless, the flow of nanofluid flow with Hall and Ion slip effect integrated with activation energy, gyrotactic microorganisms, and Cattaneo–Christov heat flux is still scarce. To fill in this gap, our aim here is to examine the three dimensional electrically conducting Tangent hyperbolic bioconvective nanofluid flow with Hall and Ion slip under the influence of magnetic field and heat transmission phenomenon past a stretching sheet. Impacts of Cattaneo–Christov heat flux, Arrhenius activation energy, and chemical reaction are also considered here. For the conversion of a non-linear system to an ordinary one, pertinent transformations procedure is implemented. By using the bvp4c MATLAB function, these equations with the boundary conditions are worked out numerically. The significant impacts of prominent parameters on velocity, temperature, and concentration profiles are investigated through graphical illustrations. The results show that the velocity of the fluid is enhanced once the Ion slip and Hall parameters values are improved. Furthermore, the concentration is improved when the values of the activation energy parameter are enhanced.

“…Sankar et al 7 attempted numerically the natural convection heat transfer in a cylindrical annular cavity with discrete heat sources on the inner wall whose purpose is to cool the chips in an effective way to prevent overheating and hot spots. Khan et al 8 followed the Buongiorno's nanodisperion concept to model mathematically the biconvection in nanodispersion transmission in stretchable object persisting porous space, Arrhenius activation energy and binary chemical reaction. Sankar et al 9 documented a report on the double diffusive convection in a vertical annulus filled with a fluid-saturated porous medium accompanying the effects of discrete source of heat and solute on the fluid flow, heat and mass transfer rates in which the location of stronger flow circulation is independent of the higher heat and mass transfer rates in the porous region.…”

Buongiorno's nanofluid model is followed to study the bioconvection in two stretchable rotating disks with entropy generation. Similarity transformations are used to handle the problem equations for nondimensionality. For the simulation of the modeled equations, Homotopy Analysis Method is applied. The biothermal system is explored for all the embedded parameters whose effects are shown through different graphs. There exists interesting results due to the effects of different parameters on different profiles. Radial velocity decreases with increasing stretching and magnetic field parameters. Temperature increases with Brownian motion and thermophoresis parameters. Nanoparticles concentration decreases on increasing Lewis number and thermophoresis parameter while motile gyrotactic microorganisms profile increases with increasing Lewis and Peclet numbers. Convergence of the solution is found and good agreement is obtained when the results are compared with published work. Natural convection has an outstanding applications in daily life. These applications are exist in petrochemical processes, cooling of electronic components, geothermal engineering, crystal growth processes, in the annular gap between the rotor and stator, thermal insulation system, food industry, growth of single silicon crystals, packed bed chemical reactors, grain storage installations, rotating systems, porous heat exchangers, fuel cells, solar ponds etc. Researchers paid extensive attention to work on convection. Venkatachalappa et al. 1 performed a study to analyze the role of rotation on the axisymmetric gravity driven complex flow in a cylindrical annulus whose side walls rotate about their axis with different angular velocities. They obtained the results for Grashof number, rotational speeds, Prandtl number, aspect ratio and compared the results with the existing data. Khan et al. 2 treated the movement in heating prevailing system of a differential type dispersion on an expanding medium using series solution. Sankar et al. 3 tested numerically the hydromagnetic field influence in axial or radial forms for natural convection of a low Prandtl number electrically conducting fluid in a vertical cylindrical annulus. Their outcomes showed that in shallow cavities the flow and heat transfer were suppressed sufficiently through an axial magnetic field and in tall cavities the radial magnetic field had an excellent output. Khan et al. 4 tested the thermal disorder, heat and mass transfer tiny dispersion movement with gyrotactic microorganisms in porous medium using heating wall information. Using the Brinkman-extended Darcy equation, Sankar et al. 5 investigated the natural convection flows in a vertical annulus filled with a fluid-saturated porous medium in which the inner wall was subjected to discrete heating, outer wall was subjected to isothermally at lower temperature and the adiabatic parts were the bottom and top walls including

The study of shape effects in nanofluids plays a vital role in the fluid flow as well as heat propagation. Hence, the different shape factors of molybdenum disulfide MoS2 on a stretchable disc with rotation under the effect of the magnetic field, chemical response, and activation energy are examined. The set of partial differential equations is converted into ordinary differential equations (ODEs) by using von Karman's transformations, and the obtained ODEs are solved by using Runge‐Kutta‐Fehlberg 45 and shooting techniques. The numerical computations are made by utilizing well‐known maple 17 software. The different physical parameter effects on velocity, temperature, and concentration curves, as well as skin friction and Sherwood numbers, are analyzed through graphs. It is noted that the larger values of solid volume fraction enhances the drag coefficient and reduces the rate of heat transfer. It is further observed that the curve of a viscous fluid is always lesser than curve of a nanofluid.
