“…In the above examination, viscoelastic fluid was not contemplated. The impact of thermal radiation and Dufour on MHD Casson fluid model and Newtonian fluid flow through non-parallel oscillatory permeable plate with Hall and ion-slip current was examined by Rajakumar et al [31] (non-Newtonian fluid), Rajakumar et al [30], Rajakumar et al [32] (Newtonian fluid). Rajakumar et al [33] and [34] investigated the influence of thermal radiation and Rivlin-Ericksen fluid model on MHD flow with chemical reaction.…”

The current examination is concerned with the influence of Dufour and thermal radiation on unsteady MHD Walter's liquid model-B flow past an impulsively started infinite vertical plate embedded in a porous medium with chemical reaction, Hall and ion-slip current. Perturbation scheme was utilized for solving non-dimensional governing equations. Computations are performed graphically to analyze the behaviour of velocity, temperature and concentration along with Skin friction, Nusselt number and Sherwood number are presented in tabular form on the vertical plate with the difference of emerging physical parameters. Finally, it is concluded that primary and secondary velocities are steeply accelerated with the incremental values of Hall and ion-slip parameter, and the same effect occurred in the case of axial and transverse components of the shearing stress. Primary and secondary velocities are enhanced with the ascending values of Dufour number. But contrast repercussions were demonstrated in the case of temperature. However, primary and secondary velocities and concentration decline with the increasing values of chemical reaction parameter but the contradicted outcome is taken place in the case of temperature. Meanwhile, primary velocity, secondary velocity and temperature are fallen with the amplified values of radiation absorption, but the inverse effect occurs in the case of Nusselt number.

“…Recently, the influence of viscous dissipation on steady MHD CF flow past an infinite nonparallel absorbent plate by means of ohmic heating was scrutinized by Rajakumar et al 46 Most recently, Rajakumar et al 47 have explored the influence of spanwise consinusoidally fluctuating temperature as well as viscous dissipation on MHD flow along with radiation absorption. Rajakumar et al 48 discussed viscous dissipation as well as Dufour's effects on MHD oscillatory inclined porous plate. Rajakumar et al 49 reported viscous dissipation on non‐Newtonian MHD fluid flow by means of radiation absorption as well as chemical reaction.…”

The current analysis concentrated on the consequence of Casson dissipative fluid and spanwise consinusoidally fluctuation temperature on unsteady magnetohydrodynamics free convective flow past a moving hot vertical permeable plate with heat generation, radiation absorption, and chemical reaction. It has imperative practical applications in plentiful fields like physiological processes, biomedical science, food processing, pharmaceutical, chemical material processing engineering, manufacturing systems, and so on. The governing partial differential equations are evaluated analytically by employing a multiple regular perturbation method. The influence of assortment physical estimators on fluid velocity, temperature, concentration, skin friction, Nusselt number, and Sherwood number was illustrated quantitatively through graphs. Eventually, it was revealed that velocity, concentration, and Sherwood number declined with the progressive values of the chemical reaction parameter. Velocity and temperature were enhanced with incremental values of Prandtl number, while the contradictory impact occurred in Nusselt number and skin friction. Meanwhile, velocity and skin friction lessened with the incremental values of the magnetic parameter and Casson fluid parameter.

“…As reported in the literature, the term MHD takes place in the momentum equation while viscous dissipation is in the energy equation. Significance of viscous dissipation on MHD free convective fluid flow through inclined porous plate was considered by Rajakumar et al 17,18 Rajakumar et al 19 considered viscous dissipation and Dufour effects on MHD free convection fluid flow through a vertical Oscillatory porous plate with ion-slip current and radiation absorption.

The current scrutinization concentrated on the consequences of viscous dissipation and chemical reaction on unsteady MHD two‐dimensional free convective fluid flow past a semi‐infinite inclined permeable plate with radiation absorption and heat generation. The governing equations are determined analytically by employing the perturbation technique. The impact of various physical estimators on velocity, temperature, concentration, skin friction, and Nusselt number along with Sherwood number were exemplified quantitatively through graphs. It was concluded that velocity declined with the incremental values of Eckert number, but contradictory impact occurred in the case of skin friction. In addition temperature, Nusselt number, as well as velocity, declined with the progressive values of radiation absorption. However, skin friction was accelerated with the augmented values of radiation absorption. Velocity accelerated, with the progressive values of angle of inclination. Concentration declined with the various augmentation values of chemical reaction as well as Schmidt number.
