“…Porous media are used in geothermal process, thermal insulation, petroleum industries, structure of solid-matrix heat transfer, etc. [33][34][35][36][37][38][39][40]. It is pertinent to mention here that the aforementioned literature for porous medium is based on Darcy's law.…”

This article reports the magnetohydrodynamic flow of second-grade nanofluid induced by a nonlinear stretching surface with deforming thickness. Darcy-Forchheimer is accounted to characterize the impact of the porous medium. Influences of thermal radiation, nonuniform heat generation/absorption and double stratification process are explored for temperature and concentration distributions. Heat and mass transfer are investigated under the influence Brownian motion and thermophoresis effects. Second-grade nanofluid is electrified under the influence of nonuniform applied magnetic field with small magnetic Reynolds number. Nonlinear partial differential equations are first converted into ordinary differential equations. The outcomes are obtained by the optimal homotopy analysis method. The impact of various physical variables that appear in velocity, temperature and concentration are sketched and discussed. Power index, second-grade variable, Darcy number and Hartman number improve the magnitude of skin friction. Thermal stratified variable enhances the heat transfer rate, while a reverse trend is noted in case of radiation. Brownian motion, solutal stratified variable and Schmidt number lower the Sherwood number.

“…It deals with formation or deposition of layers which occur as result of variation in temperature, concentrations or presence of immiscible fluids. The applications involve heat rejection into the system (like rivers, lakes, and seas), thermal energy storage vicinity (solar ponds) and heat transfer generated from thermal sources (the condensers of power plants) [22][23][24][25][26][27].…”

In this paper, we analyzed the effects of thermal radiation, chemical reaction, heat generation/absorption, magnetic and electric fields on unsteady natural convection flow and heat transfer due to nanofluid over a permeable stretching sheet. The transport equations used passively controlled boundary condition rather than actively. A similarity solution is employed to transformed the governing equations from nonlinear partial differential equations to a set of ordinary differential equations, and then solve using Keller box method. It was found that the temperature is a decreasing function with the thermal stratification due to the fact the density of the fluid in the lower vicinity is much higher compared to the upper region, whereas the thermal radiation, viscous dissipation and heat generation enhanced the nanofluid temperature and thermal layer thickness.

The present work nonlinear thermal radiation and chemical reaction effect on three-dimensional MHD flow of permeable medium analysed. We are considering introduce the Darcy-Forchheimer law along with axial and transverse velocity. Using suitable transportations the nonlinear partial differential equations are converted into ordinary differential equations. These equations are solved numerically by 4th Runge-Kutta-Fehlberg scheme with shooting procedure. We are getting unique numerical solution for distinct physical variables temperature and concentration fields are depicted. Also the heat transfer and skin friction coefficients drawn through numerical data. We are finding great results of the velocity profiles behaviors opposite trend of porosity and Forchheimer parameters, the profiles of and behavior reverse trend follows other than chemical reaction parameter, both directions of skin friction coefficient and heat transfer rates reduction.
