In this theoretical study, we have discussed the impacts of Soret and Dufour on the flow of time-dependent couple stress fluid across a stretchable curved oscillatory surface with magnetic field. The to and fro motion of the surface causes the flow phenomenon. The boundary layer flow equations depicting the flow phenomena are expressed in mathematical form by means of a curvilinear coordinates system along with some suitable similarity variables. The developed flow equations in the form of partial differential equations are then solved analytically by utilizing a valuable method called the homotopy analysis method (HAM). A detailed examination is performed to evaluate the influence of various involved parameters namely, the non-dimensional radius of curvature, couple stress parameter, magnetic parameter, the relation of the parameter of the surface oscillating frequency to its stretching rate constant and Soret and Dufour numbers on velocity field, pressure distribution, concentration and temperature distribution, rate of heat transfer, coefficient of skin friction, and rate of mass transport via graphs and are explained in detail. It is confirmed that the amplitude of velocity and pressure distribution exhibits reducing behavior with higher values of the couple stress parameter. The concentration and temperature profiles also diminish with varying time instants.

“…Due to their smaller-order magnitude, thermal-diffusion and diffusion-thermo processes are frequently overlooked in the heat transfer processes. However, as asserted by Seid et al [25], these effects cannot be disregarded in flow systems that have large concentration and temperature gradients, which mostly occur in engineering processes such as in the process of chemical manufacture, material insulation, and foam combustion. Considering this fact, several researchers believed it would be beneficial to analyze the Dufour and Soret effects on a variety system of fluid flow.…”

The widespread application of hybrid nanofluid in real applications has been accompanied by a large increase in computational and experimental research. Due to the unique characteristics of hybrid nanofluid, this study aspires to examine the steady two-dimensional mixed convection stagnation point flow of a hybrid nanofluid past a vertical plate with radiation, Dufour, and Soret effects, numerically. The formulations of the specific flow model are presented in this study. The model of fluid flow that is expressed in the form of partial differential equations is simplified into ordinary differential equations via the transformation of similarity, and then solved numerically by using the boundary value problem solver known as bvp4c in MATLAB, which implements the finite difference scheme with the Lobatto IIIa formula. Two possible numerical solutions can be executed, but only the first solution is stable and meaningful from a physical perspective when being evaluated via a stability analysis. According to the findings, it is sufficient to prevent the boundary layer separation by using 2% copper nanoparticles and considering the lesser amount of Dufour and Soret effects. The heat transfer rate was effectively upgraded by minimizing the volume fraction of copper and diminishing the Dufour effect. Stronger mixed convection would lead to maximum skin friction, mass transfer, and heat transfer rates. This important preliminary research will give engineers and scientists the insight to properly control the flow of fluids in optimizing the related complicated systems.

This study discusses the thermal and mass dispersal of ternary unsteady nanofluid flow in the existence of Soret and Dufour effects over a stretched surface with the Stefan blowing (SB) effect in porous media. The "blowing effect" is created by a large number of molecules or nanoscale particles moving from one point to another. SB is a mass transfer of species application that gives the notion of the blowing effect, as well as the Soret and Dufour effects, which are also being considered in the current study. The governing equations that pose the problem are solved using appropriate similarity variables and then translated into ordinary differential equations. Runge-Kutta-Fehlberg 45 and the shooting process are used to solve the reduced equations. The effect of the different dimensionless restrictions on the relevant profiles is visually depicted. According to the analysis, the rise in the porosity constraint will decline the velocity of the fluid. The SB parameter directly influences velocity, thermal, and concentration profiles. The Soret constraint increases concentration, whereas the Schmidt number has the opposite effect. With the addition of solid volume fraction, the rate of mass transmission and surface drag force reduces while the rate of heat dispersion increases.
