“…The study concluded that magnetic parameter produces Lorentz force that slows down the mechanism of an electrically conducting fluid. Unsteady hydromagnetic chemically reacting mixed convection flow was presented by Daba and Devaraj 11 . It was concluded in their study that increasing the magnetic parameter causes a reduction in the velocity but enhances the fluid temperature and concentration.…”

This paper examined the mechanism of both positive and negative effects of Soret‐Dufour with heat and mass transfer processes over an accelerating permeable surface. The partial differential flow equations were simplified using similarity variables, and the resulting equations were solved numerically using the spectral homotopy analysis method (SHAM). The SHAM is used in separating nonlinear equations into linear and nonlinear. The physics of each pertinent flow parameters was used to examine their influence on velocity, temperature, and concentration fields. The effect of Soret‐Dufour was examined separately, and its negative effect was used to determine its influence on velocity, temperature, and concentration fields. The result revealed that positive Soret‐Dufour enhances the boundary layer, whereas negative Soret‐Dufour parameter decreases the boundary layer. The result presented in this paper is in good agreement with existing works in literature.

“…Zeeshan et al investigated disk entropy generation due to unsteady mixed convection flow with nanofluid and Milani Shirvan et al analyzed numerical investigation of Inlet and outlet port for mixed convection optimization with nanofluids on the different square cavity. Furthermore, Daba and Devaraj examined the effect of heat absorption/source, injection/suction, viscous dissipation, and thermal radiation on unsteady, incompressible and viscous fluid due to a vertical moving mixed convection flow of MHD chemical reaction and Sharada and Shanker studied MHD Carreau nanofluid on mixed convection flow of heat and mass transfer due to exponential stretching surface. Ahmed and Rashed studied the influence of a rotating sphere on the stagnation region for unsteady MHD mixed convection flow of nanofluids.…”

This article presents a tangent hyperbolic fluid with the effect of the combination of forced and natural convection flow of nanoparticle past a bidirectional extending surface. Modified Fick's and Fourier's diffusion theories are incorporated into concentration and energy equations, respectively. Convective boundary conditions and second-order slip flow are taken in the boundary condition. Nonlinear partial differential equations result after boundary layer approximations of the mathematical formulation of the flow problem. Nonlinear high order ordinary differential equations (ODEs) are formed by applying similarity transformation on the nonlinear partial differential equations. The transformed equations are solved with the bvp4c algorithm from Matlab. The numerical solution of ODEs was obtained and the effect of interesting parameters, dimensionless velocity com-ponent along x-and y-axis, temperature, and concentration particle, Re x , Re y , Nu x , and Sh x , were presented through tables and graphs and discussed thoroughly. The results indicated that a decrease in velocity along with the y-axis results from the increasing behavior of S, M, and n. Decrease in both temperature and concentration results in an increase of α but their elongation is a result of increase in Bi. An increase in concentration results in decrease of N and S but a decrease in concentration results in the widening of Sc, Nb, and λ. Furthermore, enlargement of f − ″(0) and g − ″(0) results in increase of α and modules γ and elongation of both f − ″(0) and g − ″(0) results in increase of δ e and (Sc and Nb), respectively. A comparison with previously published literature was performed and a good agreement was found.

“…After that, the influence of the first-order chemical reaction in the presence of thermal radiation on micropolar fluid flow has been discussed by Das (2011). Daba and Devaraj (2016) obtained the numerical results on time-dependent hydromagnetic chemically reacting flow generated by a permeable vertical stretching sheet along slip and thermal radiation. Effects of radiative absorption and magnetic field on an unsteady chemically reacting convective flow over a vertical plate are described by Makinde (2012).…”

Purpose The purpose of this paper is to analyze a mathematical model for the time-dependent flow of non-Newtonian Williamson liquid because of a stretching surface. The mathematical formulation of the current model is accomplished from the momentum, energy and concentration balances by assuming a laminar, two-dimensional and incompressible flow subjected to a variable magnetic field. The study further aimed at discovering the possible effects of temperature-dependent thermal conductivity on the heat transfer characteristics. Design/methodology/approach In addition, a first-order chemical reaction is considered between the fluid and chemically reacting species. The governing transport model for Williamson fluid has been altered to ordinary differential equations via appropriate dimensionless parameters. These basic non-dimensional partially coupled differential equations of fluid motion are solved by an efficient Runge–Kutta–Fehlberg integration scheme along with the Nachtsheim–Swigert shooting technique. Findings It is found that the velocity slip parameter has a reducing impact on the skin friction coefficient. Moreover, we noticed that the Hartmann number and variable thermal conductivity parameters show prominent impacts on the velocity and temperature fields. It is also perceived that the fluid temperature shows an increasing trend with uplifting values of variable thermal conductivity. Originality/value No such work is yet published in the literature.
