“…Consider the effects of Joule heating, thermal radiation, and chemical reaction. Under the assumption of boundary layer theory, considering Darcy Forcheimmer's characteristics and [47], the governing equations of the flow can be expressed as: For reducing Eqs. 55-58 to dimensionless PDEs, the following transformation are considered:…”

This contribution proposes two third-order numerical schemes for solving time-dependent linear and non-linear partial differential equations (PDEs). For spatial discretization, a compact fourth-order scheme is deliberated. The stability of the proposed scheme is set for scalar partial differential equation, whereas its convergence is specified for a system of parabolic equations. The scheme is applied to linear scalar partial differential equation and non-linear systems of time-dependent partial differential equations. The non-linear system comprises a set of governing equations for the heat and mass transfer of magnetohydrodynamics (MHD) mixed convective Casson nanofluid flow across the oscillatory sheet with the Darcy–Forchheimer model, joule heating, viscous dissipation, and chemical reaction. It is noted that the concentration profile is escalated by mounting the thermophoresis parameter. Also, the proposed scheme converges faster than the existing Crank-Nicolson scheme. The findings that were provided in this study have the potential to serve as a helpful guide for investigations into fluid flow in closed-off industrial settings in the future.

“…They executed the analysis that the ratio of buoyancy affected the solutal and energy transportation in similar manner. Reddy et al 13 distinguished the heat production and rotatory aspects of magnetized Casson fluid over oscillatory porous plate. This investigation revealed that the isothermal plate case has higher fluid features as comparative to the ramped surface temperature situation.…”

The comparative analysis of non-Newtonian nanofluids with Newtonian conditions are addressed in this research. Oldroyd-B and Casson fluids are adopted as the non-Newtonian fluids (NNF). The generation of flow is due to bidirectionally movement of magnetized surface. Radiation and chemical reactive processes are accounted in energy and mass transportation equations. Buongiorno’s theory of nanoparticles is developed for the nanofluids analysis. The basic formulas of fluid dynamics are incorporated to formulate the physical model. The assumption of boundary-layer is utilized for the simplification of mathematical model. The arising nonlinear model of three independent variables are converted into one independent variable model using similarity constraints. The simplified mathematical model is treated analytically through the implementation of homotopic approach. The convergence of this scheme is verified through numerical benchmark and graphic illustration. The results of versatile constraints on physical quantities are addressed numerically and graphically. The comparison of results with previous published outcomes is provided in limiting approach.

The effect of Dufour on a magnetohydrodynamics (MHD) mixed convection in the presence of radiation absorption and heat sink is performed in this work. The dimensional governing equations involved here are transferred to non‐dimensional form and then solved using perturbation technique. The changes due to the effect of several relevant parameters on the velocity field temperature field and concentration field are graphically displayed. The rates of momentum transfer, heat transfer and mass transfer are also analyzed and their influence due to the related parameters are visualized graphically. Rise in Dufour parameter enhances the fluid velocity and fluid temperature. Also, the heat sink parameter lowers the fluid velocity and temperature. The chemical reactions cause a fall in the fluid's velocity, temperature and concentration.
