“…In addition boundary layer flow of non-Newtonian fluid combined with heat and mass transfer appears in solid matrix heat exchangers, desalination, damage of crops due to freezing, solar power collectors, air conditioning, cooling towers and many others (see Refs. [17][18][19][20][21]. It appears that nanofluids play a key role about heat transfer enhancement.…”

Development of human society greatly depends upon solar energy. Heat, electricity and water from nature can be obtained through solar power. Sustainable energy generation at present is a critical issue in human society development. Solar energy is regarded one of the best sources of renewable energy. Hence the purpose of present study is to construct a model for radiative effects in three-dimensional of nanofluid. Flow of second grade fluid by an exponentially stretching surface is considered. Thermophoresis and Brownian motion effects are taken into account in presence of heat source/sink and chemical reaction. Results are derived for the dimensionless velocities, temperature and concentration. Graphs are plotted to examine the impacts of physical parameters on the temperature and concentration. Numerical computations are presented to examine the values of skin-friction coefficients, Nusselt and Sherwood numbers. It is observed that the values of skin-friction coefficients are more for larger values of second grade parameter. Moreover the radiative effects on the temperature and concentration are quite reverse.

In this article, the study is to explore the series solution of magnetohydrodynamics, first‐order chemically reacting Maxwell fluid past a stretching sheet concentrated in a porous medium along with Soret and Dufour effects. The resemblance transformation is applied to convert the said time‐dependent phenomena into a family of ordinary differential equations. Then, elucidated by an analytic‐numeric approach named as homotopy analysis method (HAM) where numerical simulation is carried out carefully by a powerful software MATHEMATICA. Furthermore, the impact of disparate physical factors on the profiles of the flow model is presented vividly. The locus of the study is on the strength of the solution technique, so the error graphs disclose the fact that as the number of iterations enhanced, square residual profiles declines to 0 more sharply.

“…The flow due to stretching of a sheet has countless scientific and industrial applications such as spinning of fiber, glass blowing, metal continuous casting, manufacturing of plastic covers, paper plates production, cooling of a big magnetite plates in a bath and suspension of particles and so on.The impact of cross-diffusion on unsteady MHD mixed convection flow past a stretching surface was discussed by Alsaadi et al [16]. Abbasi et al [17] reported the Soret and Dufour effects on peristaltic transport of magneto hydrodynamic fluid with variable viscosity and found that an increase in Soret number reduces the concentration profiles.The effect of thermo diffusion on chemically reacting dusty viscous flow was studied by Reddy et al [18].…”

Abstract:The problem of an unsteady MHD Casson fluid flow towards a stretching surface with cross diffusion effects is considered. The governing partial differential equations are converted into a set of nonlinear coupled ordinary differential equations with the help of suitable similarity transformations. Further, these equations have been solved numerically by using Runge-Kutta fourth order method along with shooting technique. Finally, we studied the influence of various non-dimensional governing parameters on the flow field through graphs and tables. Results indicate that Dufour and Soret numbers have tendency to enhance the fluid velocity. It is also found that Soret number enhances the heat transfer rate where as an opposite result is observed with Casson parameter. A comparison of the present results with the previous literature is also tabulated to show the accuracy of the results.
