Radiation and chemical reaction effects on unsteady MHD free convention mass transfer fluid flow in a porous plate

Abstract

Objective: To study the effects of Radiation and chemical reaction on unsteady MHD free convection flow in a porous plate. Method: The problem is governed by coupled non-linear partial differential equations. The nondimensional equations of the problem have been solved numerically using Finite Element Method. Findings: The effects of governing parameters on the flow variables are discussed quantitatively with the help of graphs for the flow field, temperature field, concentration field, skin friction and Nusselt number. Novelty: The accuracy of the problem has been verified by comparing with the previous published work and the agreement between the results is excellent, which established confidence in the numerical results reported in this study.

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

“…In the real world, there will be tremendous applications related to MHD fluid flow, such as magnetic devices for cell severance, nuclear reactor coolants, levitating and heating liquid metals, magnetic endoscopy, metallurgical industries, molten metal pumps is an imperative substitution of convectional pumps due to their poignant parts cannot get up the molten metal temperature, bio‐medical field, magnetic drug targeting, environmental engineering and pharmaceutical industries, a salt pump is employed for nuclear reactor coolants for the reason that it is no poignant parts characteristic, metallurgical industry for stirring, and so on. Various investigators investigated huge work connected to MHD, that is, Rajakumar et al, 1 Ahmmed et al, 2 Rajakumar et al, 3 Raju et al, 4 Matta et al, 5 Riaz et al, 6 Manideep et al, 7 Anantha Kumar et al, 8 Ullah et al, 9 Mishra et al, 10 Srinivasa Raju et al, 11 and Venkatesh et al 12 examined analytical as well as experimental on MHD free convective fluid flows by means of the vertical porous plate but still, they have not discussed on MHD fluid flow along with semi‐infinite inclined permeable plate Veera Krishna et al 13 discussed second‐grade fluid on MHD oscillatory free convective flow in presence of hall current in between two normal plates, Veera Krishna et al 13 explored MHD rotating flow of non‐Newtonian fluid through permeable plate by means of hall and ion‐slip current. Chamkha 14 investigated MHD free convective flow from a nonparallel plate embedded in a thermally stratified porous medium by means of the hall effect.…”
