Analysis on Variable Fluid Viscosity of Non-Darcian Flow over a Moving Vertical Plate in a Porous Medium with Suction and Viscous Dissipation

Abstract

-An analysis is carried out to study free convective flow and heat transfer of a viscous incompressible fluid over a linearly moving vertical porous plate with suction and viscous dissipation. The fluid viscosity is assumed to vary as a linear function of temperature. The governing boundary layer equations are reduced to boundary value problem using the concept of similarity transformations. The corresponding coupled ordinary differential equation is solved numerically using the Runge Kutta fourth order method along with shooting technique. Graphical results for the dimensionless velocity and temperature distributions are shown for various values of the thermophysical parameters controlling the flow regime. Numerical values of physical quantities such as the local Skin-friction coefficient and the Local Nusselt number are presented in tabular form.

Generalized differential quadrature analysis of electro‐magneto‐hydrodynamic dissipative flows over a heated Riga plate in the presence of a space‐dependent heat source: The case for strong suction effect

“…Technically, the magnitude of the Lorentz forces is easily adjustable over time by exerting a periodic electric current of higher frequency. This control manner is more practical than other known techniques, like the porosity of rigid surfaces and their roughness impact as explained by Mutschke et al 1 In a numerical analysis by Animasaun and Aluko, 2 it was demonstrated that the magnetic field retards the motion of the fluid and the suction effect stabilizes the establishments of the hydrodynamic and thermal boundary layers. Besides this, Zaydan et al 3 found that the increase in the blowing process tends to boost the temperature distribution across the fluidic medium and lead to higher thermo-magneto-hydrodynamic stability as compared with the suction case.…”

Effects of Viscous Dissipation and Double Stratification on MHD Casson Fluid Flow over a Surface with Variable Thickness: Boundary Layer Analysis

“…The viscous dissipation effects in the entrance region heat transfer in pipes with uniform heat flux were analyzed by Ou and Cheng [13]. This attracted Animasaun and Aluko [14] to study free convective flow and heat transfer of a viscous incompressible fluid over a linearly moving vertical porous plate with suction and viscous dissipation; hence, reported that temperature function is an increasing function of Eckert number. Radiation and viscous dissipation effects on unsteady free convective flow past a moving vertical plate in a porous medium were considered by Das et al [15].…”

Unsteady Magnetohydrodynamic Flow Past a Slendering Stretching Surface with Thermophoresis and Brownian Motion

“…Anjali and Prakash [31] investigated the thermal conductivity impacts on steady incompressible magnetohydrodynamic fluid flow over a non-uniform stretching surface.Makindeet al [32] investigated the combined impacts of convective heating, Buoyancy force, magnetic field, thermophoresis and Brownian motion on stagnation point flow and heat transfer due to nanofluid stream over a stretching surface.The impact of temperature-dependentviscosity on free convective stream over a permeable plate was examined by Makinde and Ogulu [33] with thermal radiation,magnetic field and a first-order homogeneous chemical reaction. Sreedeviet al [34] focused cross diffusion and joule heating impacts of magnetohydrodynamic flow past a porous vertically stretching sheet in the presence of viscous dissipation, Buoyancy force and thermal radiation.Some researcher's [35][36][37][38][39] have discussed and reported the effects of non-linear thermal radiation over a vertical plate.…”
