Significance of Casson dissipative fluid and spanwise cosinusoidally fluctuating temperature on unsteady MHD free convective flow past a hot vertical permeable plate with radiation absorption and chemical reaction

Abstract

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.

Viscous dissipation and radiation absorption effects on unsteady MHD free convective fluid flow past an inclined porous plate with chemical reaction

“…Anil Kumar et al 29 examined MHD fluid flow by means of thermal radiation along with impulsively started vertical plates. Impact of spanwise cosinusoidally fluctuating temperature and Casson dissipative fluid on unsteady MHD flow over a vertical plate with radiation absorption has been reported by Rajakumar et al, 30 Nandeppanavar et al 31 explored nonlinear thermal radiation on MHD free convection fluid flow along moving vertical plate. Shankar Goud et al 32 have contemplated the influence of thermal radiation on MHD natural convection flow over a normal plate in presence of a chemical reaction.…”

Chemical reaction and radiation impact on unsteady free convective flow through a porous medium past an infinite oscillatory vertical plate

“…Chemical reactions may be classified as heterogeneous or homogeneous depending on whether they occur at an interface or in a single-phase volume reaction. The impact of chemical reactions on an unsteady MHD flow over a heated vertical permeable plate with radiation absorption was examined by Rajkumar et al [17]. Endalew et al [18] investigated the impacts of chemical reactions, radiation and an inclined magnetic field on an oscillating slanted plate under temperature and concentration variations over time.…”
