“…Hayat et al [29] investigated the flow of Ree-Eyring nanofluid with entropy generation and Arrhenius activation energy with binary chemical reaction between two rotating disks where velocities are boost up with higher values of Reynolds number while both the entropy generation rate and Bejan number are decreased at lower disk. Khan et al [30] modeled and solved the problem of entropy generation in rotating flow of Casson nanofluid between stretching disks in the presence of thermal radiation, chemical reaction, heat source/sink with slip boundary conditions. Their simulation results revealed that axial velocity and Bejan number are diminished with the increments of Casson nanofluid parameter.…”

The study concerns with the mechanical characteristics of rotating system of two double disks. Hall current effect, entropy generation, Arrhenius activation energy and binary chemical reactions are investigated in heat and mass transfer bioconvection flow of Maxwell nanofluid. Brownian motion and thermophoresis with thermal radiation and buoyancy effects are encountered in the governing equations. The mechanical system has been investigated by the governing equations and boundary conditions which are simplified by the use of suitable similarity transformations. Optimal homotopy analysis method is implemented to obtain the series solution of non‐linear ordinary differential equations. Physical behaviors of heat and mass transfer flow with entropy generation are investigated through the effects of embedded parameters.

“…Ahmad and Nadeem [39] used the Thomson and Troian auxiliary conditions to investigate the entropy minimization in stagnation point flow of a hybrid nanofluid with Cattaneo-Christov heat and mass flux theory, variable mass diffusivity and viscosity, activation energy past a nonlinear porous stretching sheet. Khan et al [40] applied the shooting method to compute the solution of entropy generation in axisymmetric flow of non-Newtonian nanofluid between two parallel rotating disks where Bejan number was noted to decrease with increasing the parameter of Casson nanofluid. Khan et al [41] examined the entropy generation for single/multi walled carbon nanotubes with homogeneous-heterogeneous chemical reactions and heat transfer.…”

Lorentz Forces Effects on the Interactions of Nanoparticles in Emerging Mechanisms with Innovative Approach

This paper focuses on advances in the understanding of both the fundamental and applied aspects of nanomaterials. Nanoparticles (titania and graphene oxide) in water-based fluid lying on a surface incorporating the leading edge accretion (or ablation) are analyzed. Entropy generation rate is also considered. The Hall current effect is induced in the flow of hybrid nanofluid, due to which the two-dimensional study converts into three-dimensional space. Similarity transformations convert the equations of momentum, heat transfer, nanoparticles volume fraction and boundary conditions into non-dimensional form. Mathematica software is used to obtain the computation through homotopy analysis method. Analysis is provided through the effects of different parameters on different profiles by sketching the graphs. Flow, heat transfer and nanoparticles concentration in TiO2/H2O, as well as GO-TiO2/H2O, are decreased with increasing the Stefan blowing effect, while entropy generation rate elevates upon increasing each parameter. Both of the velocity components are reduced with increasing the Hall parameter. Streamlines demonstrate that trapping is increased at the left side of the surface. The obtained results are compared with the published work which show the authentication of the present work.

“…In this examination, they likewise viewed warm radiation and thick dispersal impacts for the stream framework over an extending sheet. Khan et al 37 have contemplated the impacts of synthetic entropy optimization on the axisymmetric flow of Casson nanoliquid between radiative extending plates with warm radiation, chemical response, and temperature that have been scientifically demonstrated and re‐created by means of the collaboration of slip limit conditions. Liao 38,39 has recognized that this strategy is fast convergent to the estimated solution, and for the result of nonlinear problems, it is more acceptable.…”

In this paper, we analyzed Darcy‐Forchheimer three‐dimensional bioconvection Casson nanofluid flow due to a rotating disk with entropy generation. The flow is considered with the outcome of thermal radiation and Arrhenius activation energy. For nondimensionality, we utilized the similarity transformations to deal with the problem equations. The homotopy analysis method is applied for the re‐creation of the modeled equations. The biothermal framework is investigated for all the implanted parameters whose impacts are observed through various graphs. There exist intriguing outcomes due to the impacts of various parameters on various distributions. Nanoparticles' concentration diminishes with expansion of the Schmidt parameter and Brownian motion constraint, whereas motile gyrotactic microorganisms' distribution diminishes with expansion of bioconvection Peclet and Lewis numbers. The entropy generation rate increases with the increase of the Brinkman number, Casson fluid parameters, and magnetic parameters. Enrichment in the Reynolds number (Rer) leads to a decrease in the entropy generation rate. Moreover, Bejan number reduces with escalating values of the magnetic parameter, Brinkman number, and Casson fluid parameters. Bejan number (Be) is higher for larger Reynolds numbers and temperature difference parameter.
