“…In another exploration, impact of Soret-Dufour on MHD heat and mass transport of Walter's B liquid fluid was considered by Idowu and Falodun [15]. The recent study of Idowu and Falodun [28] was based on mechanism of Soret-Dufour on the flow of non-Newtonian fluid. In another study considered by Idowu and Falodun [29], influence of Soret-Dufour with variable viscosity and thermal conductivity was extensively discussed in a hot environment.…”

This study explored the flow of an electrically conducting and chemically reacting nanofluid over a semi‐infinite porous vertical plate under the influence of Soret–Dufour and nonlinear buoyancy force. The flow analysis consists of partial differential equations (PDEs). These equations were nondimensionalized via nondimensional quantities into coupled nonlinear PDE and solved numerically using spectral relaxation method. Numerical computations of all flow parameters for velocity, temperature along with concentration are presented in diagrams. The result shows that an upsurge in the value of the radiation parameter enhances both velocities along with temperature profiles, respectively. This is true because the temperature at the plate is much when there is an increase in the radiation parameter. The present results were compared with the previously published result and were found to be in excellent agreement.

In the present investigation, Soret–Dufour and multislip's impact on magnetohydrodynamics (MHD) Casson fluid flow encompassing variable thermophysical features in the nonlinear convection process is analyzed. It is believed that to any effective heat and mass transfer enhancement, the relaxation of such fluid and material time along with the thermo‐physical features, are well estimated. In this model, a magnetic field of nonuniform strength is applied perpendicular to the slendering sheet with variable thickness, and nonlinear convection flow is considered in this generalized heat flux examination. An appropriate similarity variable is implemented on the governing equations embedding the variable viscosity, thermal conductivity, and generalized Fourier's law to drive ordinary differential equations. Galerkin weighted residual approach is utilized to calculate the flow field among other flow characteristics. The novel flow features are discussed therein. Modified Fourier and multislip's parameters are seen to have downsized the velocity and temperature field greatly. Thermal and solutal buoyancy effects are more pronounced in nonlinear form compared to the linear model. Dufour number influences both velocity and energy fields positively but negates the concentration field, while the Soret number gives an opposing characterization.

“…Megahed 10 examined Williamson fluids flow because of a nonlinearly stretching sheet. The recent study of Idowu and Falodun 11 elucidates the flow of Casson liquid over an Inclined plate. They employed the spectral homotopy analysis method (SHAM) to solve their model equations and noticed a large Casson term degenerates the velocity.…”

This communication examines heat alongside mass transport in a nonlinear free convection magnetohydrodynamics (MHD) non‐Newtonian fluid flow with thermal radiation and heat generation deep‐rooted in a thermally stratified penetrable medium. The Casson and Williamson fluid considered in this communication flos simultaneously across the boundary layer and are mixed together. The model of heat alongside mass transport is set up with chemical reaction and thermal radiation alongside heat generation to form a system of partial differential equations (PDEs). Appropriate similarity variables are used to simplify the PDEs to obtain systems of coupled ordinary differential equations. An efficiently developed numerical approach called the spectral homotopy analysis method was used in providing solutions to the transformed equations. A large value of Casson term is observed to degenerate the velocity plot while the Williamson parameter enhances the velocity profile. The parameter of thermal stratification is found to enhance the rate of heat transport within the boundary layer. An incremental value of the magnetic parameter declines the velocity of the fluid and the entire boundary layer thickness. The present result was compared with previous studies and was seen to be in good agreement.
