Bingham fluid through porous parallel plates with Ion-slip and Hall currents has been studied numerically. The non-linear PDEs, governing the problem under assumptions, have been transformed into dimensionless non-linear PDEs by using usual transformations. The obtained dimensionless governing equations have been solved numerically by applying the explicit finite difference method (FDM) with the help of MATLAB R2015a tool. The time sensitivity test is performed for the steady-state solution and is obtained at dimensionless time τ=4.00. It is also observed that the secondary velocity reaches the steady-state more gradually than the primary velocity and temperature profiles. The appropriate mesh space (m=40 and n=40) is obtained by the mesh sensitivity test. The impact of various interesting parameters on the primary velocity, secondary velocity and temperature profiles, also on the local Nusselt number and shear stress have been analyzed and discussed through the graph in details. Finally, a qualitative and quantitative comparison with the published results has been discussed.

“…Considering the importance of the problems of MHD free convective flow of electrically conducting fluids, deep and extensive investigations have been carried out by several researchers in the past.

“…Darcian drag force induces due to permeability of the porous medium and it plays a significant role in MHD free convection boundary layer flows because it modify the drag force arising from the magnetic field (Lorentz force). Ibrahim et al [2], Chaudhary and Jain [3], Postelnicu [4], Beg et al [6], Chamkha and Aly [10], Seth et al [11][12][13], Das [14], Khan et al [15], Prasad et al [16], Hossain et al [19], Balamurugan et al [20], Swetha et al [21] and Seth and Sarkar [23] investigated MHD free convection flow of an electrically conducting fluid in a porous medium considering different aspects of the problem. Rotating fluid system produces two types of forces, namely, Coriolis force and centrifugal force.…”

“…In hydromagnetic fluid flows, both the Coriolis and Lorentz forces are comparable and Coriolis force induces motion in secondary flow direction. Keeping these facts into consideration many, researchers, namely, Raptis and Singh [25], Kythe and Puri [26], Tokis [27], Nanousis [28], Mbeledogu and Ogulu [5], Das [14], Deka et al [17], Hossain et al [19] and Seth et al [12] investigated the combined influence of Coriolis and Lorentz forces on MHD free convection flows. The motion of partially-ionized fluid with low density (plasmas) in the presence of a strong magnetic field induces two electromagnetic phenomena, namely, Hall effect and ion-slip effect (Cramer and Pai [29]).…”

A mathematical analysis of unsteady MHD free convective flow of an incompressible, chemically reacting, electrically and thermally conducting fluid past an oscillating vertical plate embedded in a fluid saturated porous medium in a rotating system taking Hall and ion-slip currents into account is presented. The plate temperature is considered to be linear function of time for a certain time interval and thereafter it is kept at a constant temperature while species concentration at the surface of the plate is considered to be linear function of time. The governing coupled partial differential equations are solved by using Laplace transform technique. Two particular cases of interest are considered to obtain the solution of velocity field i.e. (i) when the natural frequency due to rotation and Hall current is different from the frequency of oscillations, and (ii) when the natural frequency due to rotation and Hall current is equal to the frequency of oscillations (i.e. the case of resonance). The expressions for skin friction, Nusselt number and Sherwood number are also derived. To analyze the flow features of the present problem the velocity, temperature and concentration distributions are depicted graphically whereas the skin friction at the plate, Nusselt number and Sherwood number are presented in tabular form for various values of different pertinent flow parameters.

This study presents the numerical solution of velocity and temperature fields based on mass conservation, momentum and energy balances for the time-dependent Couette-Poiseuille flow of Bingham materials through channels. The channel flow of Bingham fluid concerns the flow of cement paste in the building industry and the mudflow in the drilling industry. The specific aim is to introduce the magnetohydrodynamic (MHD) phenomena specified by both Ion-slip and Hall currents into the non-isothermal channel flow in a theoretical approach. The Bingham constitutive equation is formulated by the generalized Newtonian fluid technique and solved by employing the explicit Finite Difference Method (FDM) using the MATLAB R2015a and Compaq Visual FORTRAN 6.6a both. For the exactness of numerical performance estimations, the criteria for stabilization and the convergence factor are analyzed. The velocity and temperature profiles are discussed individually at the moving and stationary walls of the channel. It is observed that magnetohydrodynamic phenomena accelerate the flow, and the temperature distributions reach the steady-state situation earlier than velocity distributions. Furthermore, the dominance of MHD parameters on the velocity distributions, shear stress, temperature distributions, and Nusselt number are discussed.
