Hydromagnetic Unsteady Mixed Convection Flow Past an Infinite Vertical Porous Plate

Abstract

An approximate analysis of unsteady mixed convection flow of an electrically conducting fluid past an infinite vertical porous plate embedded in porous medium under constant transversely applied magnetic field is presented here. The periodic transverse suction velocity is applied to the surface due to which the flow becomes unsteady. The surface is kept at oscillating wall temperature. Analytical expressions for the transient velocity, temperature, amplitude and phase of the skin-friction and the rate of heat transfer are obtained and discussed in detail with the help of graphs, under different parameter values.

Computer Simulation of Heat and Mass Transfer Effects on Nanofluid Flow of Blood Through an Inclined Stenosed Artery With Hall Effect

“…When an external DOI 10.2478/ama-2024-0017 Computer Simulation of Heat and Mass Transfer Effects on Nanofluid Flow of Blood Through an Inclined Stenosed Artery with Hall Effect 130 magnetic field is used during magnetic resonance imaging, the impact of the magnetic field on blood flow via arteries is significant. Numerous studies [17][18][19][20][21] have examined the flow issues of viscous incompressible fluid via various geometries with the Hall effect. In the study by Ramzan et al [22], investigation of the 3D nanofluid flow took into account Hall and ion slip effects, Arrhenius activation energy and Cattaneo-Christov heat flux.…”

Unsteady MHD mixed convection flow past an oscillating plate with heat source/sink

“…The peak value of the velocity increases rapidly near the porous plate as buoyancy force for heat transfer increases and then decays the free stream velocity. Sharma, Chand and Chaudhary (2011) report an approximate analysis of unsteady mixed convection flow of an electrically conducting fluid past an infinite vertical porous plate embedded in porous medium under constant transversely applied magnetic field, where The transient velocity increases with increase in distance from plate until it attains its maximum value (nearly y = 1), after which it decreases. Osman et al (2011) studied thermal radiation and chemical reaction effects on the unsteady MHD convection through a porous medium bounded by an infinite vertical plate with heat source/sink.…”
