“…These include the studies of Kumari and Radhakrishnamacharya [42] and Ramesh and Devakar [43] which have also incoporated slip effects and couple stress rheological effects. Other researchers have explored magnetohydrodynamic transport with a range of different formulations including Lorentz body forces [44], streamwise magnetic field [45], ferrohydrodynamics [46], magnetic nanofluids [47], magnetic induction [48] and mesoscopic hydromagnetic heat transfer [49]. Furthermore magnetohydrodynamic micropumps (which propel conductive liquids which are subjected to perpendicular applied electric and magnetic fields across a microchannel via the Lorentz force)…”

The influence of transverse magnetic field on time-dependent peristaltic transport of electrically-conducting fluids through a microchannel under an applied external electric field with induced electric field effect is considered, based on lubrication theory approximations.The electrohydrodynamic (EHD) problem is also simplified under the Debye linearization.Closed-form solutions for the linearized dimensionless boundary value problem are derived.With increasing Hartmann number, the formation of bolus in the regime (associated with trapping) is inhibited up to a critical value of magnetic field. Flow rate, axial velocity and local wall shear stress are strongly decreased with greater Hartmann number whereas pressure difference is enhanced with higher Hartmann number at low time values but reduced with greater elapse in time. With greater electro-osmotic parameter (i.e. smaller Debye length), maximum time-averaged flow rate is enhanced, whereas the axial velocity is reduced. An increase in electrical field parameter (i.e. maximum electro-osmotic velocity) causes an increase in maximum time-averaged flow rate. The simulations find applications in electromagnetic peristaltic micro-pumps in medical engineering and also "smart" fluid pumping systems in nuclear and aerospace industries.

“…Researchers have devoted considerable attention to the study of MHD flow problems focusing on non-Newtonian fluids becauseoof its broad applicationsiin theffields of engineeringaand industrial manufacturing [19][20][21][22]. Some examples of these areas are energy generators MHD, melting of metals by the application of a magnetic field in an electric furnace, the cooling nuclear reactors, plasma studies, the use of non-metallic inclusions in theppurification of molten metals and extractions of geothermal energy [23][24][25][26][27]. The appliedmmagnetic field aswwell as porousmmatrix may playaan important roleiin controlling momentum andhheat transferiin the boundary layer flow of different fluids in the process of wire coating.…”

Abstract:Wire coating process is a continuous extrusion process for primary insulation of conducting wires with molten polymers for mechanical strength and protection in aggressive environments. Nylon, polysulfide, low/high density polyethylene (LDPE/HDPE) and plastic polyvinyl chloride (PVC) are the common and important plastic resin used for wire coating. In the current study, wire coating is performed using viscoelastic third grade fluid in the presence of applied magnetic field and porous medium. The governing equations are first modeled and then solved analytically by utilizing the homotopy analysis method (HAM). The convergence of the series solution is established. A numerical technique called ND-solve method is used for comparison and found good agreement. The effect of pertinent parameters on the velocity field and temperature profile is shown with the help of graphs. It is observed that the velocity profiles increase as the value of viscoelastic third grade parameter β increase and decrease as the magnetic parameter M and permeability parameter K increase. It is also observed that the temperature profiles increases as the Brinkman number Br, permeability parameter K, magnetic parameter M and viscoelastic third grade parameter (non-Newtonian parameter) β increase.

Abstract:The most important plastic resins used for wire coating are polyvinyl chloride (PVC), nylon, polysulfone, and low-/high-density polyethylene (LDPE/HDPE). In this article, the coating process is performed using elastic-viscous fluid as a coating material for wire coating in a pressure type coating die. The elastic-viscous fluid is electrically conducted in the presence of an applied magnetic field. The governing non-linear equations are modeled and then solved analytically by utilizing an Adomian decomposition method (ADM). The convergence of the series solution is established. The results are also verified by Optimal Homotopy Asymptotic Method (OHAM). The effect of different emerging parameters such as non-Newtonian parameters α and β, magnetic parameter Mand the Brinkman number Br on solutions (velocity and temperature profiles) are discussed through several graphs. Additionally, the current results are compared with published work already available.
