Similar to other fluids (Newtonian and non-Newtonian), micropolar fluid also exhibits symmetric flow and exact symmetric solution similar to the Navier–Stokes equation; however, it is not always realizable. In this article, the Buongiorno mathematical model of hydromagnetic micropolar nanofluid is considered. A joint phenomenon of heat and mass transfer is studied in this work. This model indeed incorporates two important effects, namely, the Brownian motion and the thermophoretic. In addition, the effects of magnetohydrodynamic (MHD) and chemical reaction are considered. The fluid is taken over a slanted, stretching surface making an inclination with the vertical one. Suitable similarity transformations are applied to develop a nonlinear transformed model in terms of ODEs (ordinary differential equations). For the numerical simulations, an efficient, stable, and reliable scheme of Keller-box is applied to the transformed model. More exactly, the governing system of equations is written in the first order system and then arranged in the forms of a matrix system using the block-tridiagonal factorization. These numerical simulations are then arranged in graphs for various parameters of interest. The physical quantities including skin friction, Nusselt number, and Sherwood number along with different effects involved in the governing equations are also justified through graphs. The consequences reveal that concentration profile increases by increasing chemical reaction parameters. In addition, the Nusselt number and Sherwood number decreases by decreasing the inclination.

The numerical computations of Soret-Dufour aspects in hydromagnetics nanofluid flow in thermal stratified porous medium under radiated chemical reaction are developed. The unique similarity transformations lead to reduce the partial differential system into expressions of ordinary ones. Keller-box approach is adopted to express the numeric solutions. The impacts of embedded flow parameters on the different flow profiles signifying velocity, concentration and temperature of nanofluid are discussed via graphs. The values of −θ � (0) , − � (0) and −f �� (0) in relation with the variation in sundry physical parameters are examined through numerical benchmarks. The numerical results in special cases agreed with published work showing the validity of formulated problem. It can be seen that the temperature profile enhances for cumulative values of Brownian motion and thermophoretic impacts. In addition, the enhancement in Dufour factor declines the temperature profile. On contrast, larger the Soret parameter results an increase in concentration profile. On the other hand, chemical reaction shows direct relation with temperature profile.

The principal objective of the current study is to analyze the Brownian motion and thermophoretic impacts on micropolar nanofluid flow over a nonlinear inclined stretching sheet taking into account the Soret and Dufour effects. The compatible similarity transformations are applied to obtain the nonlinear ordinary differential equations from the partial differential equations. The numerical solution of the present study obtained via the Keller-Box technique. The physical quantities of interest are skin friction, Sherwood number, and heat exchange, along with several influences of material parameters on the momentum, temperature, and concentration are elucidated and clarified with diagrams. A decent settlement can be established in the current results with previously published work in the deficiency of incorporating effects. It is found that the growth of the inclination and nonlinear stretching factor decreases the velocity profile. Moreover, the growth of the Soret effect reduces the heat flux rate and wall shear stress.
