“…Nanofluid has now attracted significant interest from researchers, and boundary layer models have been studied under various settings [11][12][13]. After a long discontinuity in the theoretical works of the Sutterby boundary layer fluid flow, some numerical investigations of the Sutterby fluid under the Cattaneo-Christov heat flux [14,15], Soret and Dufour effect [16], peristaltic flow [17][18][19], squeezed flow [20], Joule heating effect [21], homogeneous-heterogeneous reactions [22], and hybrid nanoparticles [23] have been reported recently.…”

The present theoretical work endeavors to solve the Sutterby nanofluid flow and heat transfer problem over a permeable moving sheet, together with the presence of thermal radiation and magnetohydrodynamics (MHD). The fluid flow and heat transfer features near the stagnation region are considered. A new form of similarity transformations is introduced through scaling group analysis to simplify the governing boundary layer equations, which then eases the computational process in the MATLAB bvp4c function. The variation in the values of the governing parameters yields two different numerical solutions. One of the solutions is stable and physically reliable, while the other solution is unstable and is associated with flow separation. An increased effect of the thermal radiation improves the rate of convective heat transfer past the permeable shrinking sheet.

“…Their study concluded that the chemical reaction parameter decreases the concentration profile as expected. Ahmad et al [7] studied the effects of double stratification by examining chemically reactive fluid flow. Their flow analysis was done using the homotopy analysis method and the study concluded that for much Schmidt number, solutal stratified and chemical reaction and solutal stratified parameter, there is an enhancement in the concentration field.…”

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 real life applications, summer and winter stratifications prevent the fluid from mixing. This phenomenon has great impact on the phytoplankton (algae) populations, fisheries management and water supply quality, deficiency of dissolved oxygen in the lower region of ponds, lakes and rivers. Thus, our main moto in this article is to highlight the features of mixed convection in Powell-Eyring fluid deformed by an inclined stretchable sheet. Characteristics of heat transfer are exposed via thermal stratification. The solutal stratification and chemical reaction of first order are accounted to elaborate the nature of mass transfer. The coupled non-linear equations with ordinary derivatives are acquired after utilizing suitable transformation. The homotopic approach is adopted to accomplish the convergent series solution. Analysis of various emerging parameters on the fluid's temperature, velocity and concentration fields is elaborated through graphs. Surface drag, Sherwood and Nusselt numbers are studied through graphical data corresponding to numerous parameters. In conclusion, dominant solutal and thermal stratified parameters are responsible for reduction of concentration and temperature fields, respectively, which enables us to prevent the formation of fluid layers with different density regions.
