“…Non-Newtonian fluid with viscoelastic characteristics can help in improving lubricants of industrial machines and technology devices' efficiency. As such, Nayak et al [ 3 ] examined entropy optimization of the hydromagnetic non-Newtonian nanomaterial with a joint approach for heat transfer intensification and solar energy absorber. The problem was solved numerically, and the result shows that a rise in the Weissenberg number enhanced fluid velocity.…”

This research considers the third-grade liquid flow and criticality branched-chain of a thermal reaction in a Couette generalized medium with a nonlinear viscosity model. A dimensionless transformation of the system momentum and heat equations are carried out. Compared with the diffusion coefficient, the flow is stimulated by initiation reaction rate, reaction branch-chain order, non-Newtonian term, thermal Grashof number, and pressure gradient. The reactive fluid is fully exothermic with consumption of the material, and the heat exchange in the system is greater than the exchange of heat with the ambient. A semianalytical collocation weighted residual scheme is employed for the branch-chain slice bifurcation, dimensionless energy, and momentum solutions. The results show that exponential decreases in the thermal fluid viscosity can help in controlling the boundless heat produced by the Frank-Kamenetskii term and initiation reaction rate. Therefore, the results will help in stimulating positive combustion processes.

“…Usually, a smaller volume fraction of particles is required to enhance the transfer of energy as differentiated to microparticle slurries. Nayak et al 2 investigated the magnetohydrodynamic (MHD) flow of non‐Newtonian nanofluids with entropy optimization and explored there how their study led an approach to good absorber of solar energy and intensification of heat transport. Sithole et al 3 studied the unsteady MHD Maxwell nanofluid motion over a reduction sheet under the influence of Brownian motion, thermophoretic mechanism, convective, and slip boundary situations.…”

“…Nayak et al 6 investigated the impacts of the magnetic field and thermal radiation on three‐dimensional (3D) stretched flow of nanofluid subject to the Brownian motion. Many researchers 2,7‐9 studied that the thermal conductivity to be enhanced by an excess of 25% with a very small nanoparticle volume concentration. Pak and Cho 10 reported the heat transfer in two types of nanofluids and established that on increasing the volume fraction of suspended solid particles and Reynolds number, the corresponding Nusselt number of the isolated liquid enhances.…”

The present analysis is meant to explore the computational solution of the problem dealing with the impact of relaxation-retardation viscous dissipation and chemical reaction on the flow of Oldroyd-B nanofluid over a Riga plate. Hyperbolic time-varying boundary conditions are taken into consideration. The basic modeled problem being transformed into nonlinear differential equations are solved numerically by efficient fourth-order Runge-Kutta method along with shooting technique. Characteristics of controlling parameters on velocity, temperature, and concentration along with skin friction, Nusselt number, and Sherwood number profiles are presented with the help of well-featured graphs. The relaxation and retardation parameters affect well flow profiles. In addition, an accelerated flow pattern

“…Due to the huge applicability of such fluids in industry, researchers are still investigating the transport mechanism of energy and solute for such fluids. Non‐Newtonian nanofluids use different fluids as the base fluid 5,6 . Nayak et al 7 have shown the heat transfer impact for a lubricant nanofluid flow over an inclined rotating disk.…”

Microorganisms play a vital role in understanding the ecological system. The motions of micororganisms are self‐propelled while the impact of thermophoresis and Brownian motion property of nanoparticle shows more challenges in biotechnological and medical applications. The present problem is based on the understanding of double‐dispensed bioconvection for a Casson nanofluid flow over a stretching sheet. Suction phenomenon is introduced at the surface of the stretching sheet along with the convective boundary condition. The convection and movement of the microorganisms are assisted by an applied magnetic field, nonlinear thermal radiation, and first‐order chemical reaction. The governing equations are highly coupled and thus we used the spectral quasilinearization method to solve the governing equations. The study of the residual errors on the systemic parameters had given a confidence with the present results. The final outcomes are displayed through graphs and tables. The thermal dispersion coefficient shows a positive response in the temperature while a similar response is observed for the concentration with solutal dispersion coefficient. The response is reversible for the heat transfer rate at the surface with thermal dispersion coefficient. The density of the motile microorganism at the surface decreases with increase in the Casson number, thermal dispersion coefficient, and solute dispersion coefficient, while an opposite phenomenon was observed with increase in the density ratio of the motile microorganism.
