Abstract:
Taylor–Couette flow in the presence of a magnetic field is a problem belonging to classical hydromagnetics and deserves to be more widely studied than it has been to date. In the nonlinear regime the literature is scarce. We develop a formulation suitable for solution of the full three-dimensional nonlinear hydromagnetic equations in cylindrical geometry, which is motived by the formulation for the magnetic field. It is suitable for study at finite Prandtl numbers and in the small Prandtl number limit, relevant to laboratory liquid metals. The method is used to determine the onset of axisymmetric Taylor vortices, and finite-amplitude solutions. Our results compare well with existing linear and nonlinear hydrodynamic calculations and with hydromagnetic experiments.

Abstract:
Boundary-layer equations are solved for the hydromagnetic problem of two-dimensional Hiemenz flow, for a micropolar, viscoelastic, incompressible, viscous, electrically conducting fluid, impinging perpendicularly onto a plane in the presence of a transverse magnetic field. The governing system of equations is first transformed into a dimensionless form. The resulting equations then are solved by using the Runge–Kutta numerical integration procedure in conjunction with shooting technique. Numerical solutions are presented for the governing momentum and angular-momentum equations. The proposed approximate solution, although simple, is nevertheless sufficiently accurate for the entire investigated range of values of the Hartman number. The effect of micropolar and viscoelastic parameters on Hiemenz flow in hydromagnetics is discussed.PACS No.: 46.35

Abstract:
Similar to other fluids (Newtonian and non-Newtonian), micropolar fluid also exhibits symmetric flow and exact symmetric solution similar to the Navier–Stokes equation; however, it is not always realizable. In this article, the Buongiorno mathematical model of hydromagnetic micropolar nanofluid is considered. A joint phenomenon of heat and mass transfer is studied in this work. This model indeed incorporates two important effects, namely, the Brownian motion and the thermophoretic. In addition, the effects of magnetohydrodynamic (MHD) and chemical reaction are considered. The fluid is taken over a slanted, stretching surface making an inclination with the vertical one. Suitable similarity transformations are applied to develop a nonlinear transformed model in terms of ODEs (ordinary differential equations). For the numerical simulations, an efficient, stable, and reliable scheme of Keller-box is applied to the transformed model. More exactly, the governing system of equations is written in the first order system and then arranged in the forms of a matrix system using the block-tridiagonal factorization. These numerical simulations are then arranged in graphs for various parameters of interest. The physical quantities including skin friction, Nusselt number, and Sherwood number along with different effects involved in the governing equations are also justified through graphs. The consequences reveal that concentration profile increases by increasing chemical reaction parameters. In addition, the Nusselt number and Sherwood number decreases by decreasing the inclination.

Abstract:
We investigate magnetic Taylor–Couette flow in the presence of an imposed axial magnetic field. First we calculate nonlinear steady axisymmetric solutions and determine how their strength depends on the applied magnetic field. Then we perturb these solutions to find the critical Reynolds numbers for the appearance of wavy modes, and the related wave speeds, at increasing magnetic field strength. We find that values of imposed magnetic field which alter only slightly the transition from circular-Couette flow to Taylor-vortex flow, can shift the transition from Taylor-vortex flow to wavy modes by a substantial amount. The results are compared to those for onset in the absence of a magnetic field.

Abstract:
An exact periodic solution for the hydromagnetic unsteady flow of an incompressible fluid with constant properties is obtained. The hydrodynamic (HD) and the hydromagnetic (HM) cases are studied. The flow field here is a generalization of the well-known Couette flow, in which one wall is at rest and the other wall oscillates in its own plane about a constant mean velocity. In order to have some suggestions about the approximate solutions, the exact solution is compared with its own approximate form.

Abstract:
The stability of viscous flow between rotating cylinders in the presence of a constant axial magnetic field is considered. The boundary conditions for general conductivities are examined. It is proved that the Principle of Exchange of Stabilities holds at zero magnetic Prandtl number, for all Chandrasekhar numbers, when the cylinders rotate in the same direction, the circulation decreases outwards, and the cylinders have insulating walls. The result holds for both the finite gap and the narrow gap approximation.

Abstract:
One of the extraordinary properties of the Sun is the observed range of motion scales from the convection granules to the cyclic variation of magnetic activity. The Sun's magnetic field exhibits coherence in space and time on much larger scales than the turbulent convection that ultimately powers the dynamo. Motivated by the scale separation considerations, in this thesis we study the parametric scale selection of dynamo action. Although helioseismology has made a lot of progress in the study of the solar interior, the precise motions of plasma are still unknown. In this work, we assume that the model flow is forced with helical viscous body forces acting on different characteristic scales and weak and strong large-scale shear flows that are believed to be present near the base of the convection zone. In this thesis, we look for numerical evidence of a large-scale magnetic field relative to the characteristic scale of the model flow. The investigation is based on the simulations of incompressible MHD equations in elongated triply-periodic domains. To commence the investigation, a linear stability analysis of the coarsening instability in a one-dimensional periodic system is performed to study the stability threshold in the mean-field limit that assumes large scale separation in the system. The simulations are used to discriminate between different forms of the mean-field α -effect and domain aspect ratio. The notion of scale selection refers to methods for estimating characteristic scales. We define the dynamo scale through the characteristic scales of the underlying model flow, forcing and the realised magnetic field. The aspect ratio of the elongated domains plays a crucial role in all considered cases. In Part II, we examine the dynamo generated by the imposed model flows. The transition from large-scale dynamo at the onset to small-scale dynamo as we increase Rm is smooth and takes place in two stages: a fast transition into a predominantly small-scale magnetic energy state and a slower transition into even smaller scales. The long wavelength perturbation imposed on the ABC flow in the modulated case is not preserved in the eigenmodes of the magnetic field. In the presence of the linear (semi-linear shearing-box approximation) and the sinusoidal shearing motions, the field again undergoes a smooth transition at the slow non-sheared rate, which is associated with the balance of the advection and diffusion terms in the induction equation. Part III considers the nonlinear extension of the analysis in Part II, where the incompressible cellular and sheared flows interact with the exponentially growing magnetic field via the Lorentz force in the dynamical regime. Both sheared and non-sheared helical cellular flows become unstable to large-scale perturbations even in the limit of high viscosity. Due to the helical properties of the imposed forcing, the inverse cascade of helicity leads to energy accumulation in the largest scales of the domain, albeit the characteristic lengthscale exhibits the transitional nature at a highly reduced rate in the mean-field limit. As Rm is increased, the transition resembles that of the kinematic regime. The unique properties of the anisotropic shear reduce the componentality of the system, which in turn is able to half the rate of transition from the large-scale dynamo at the onset to a small-scale one.

Magnetohydrodynamic (MHD) boundary layer flow of an electrically conducting viscous incompressible fluid with a convective surface boundary condition is frequently encountered in many industrial and technological applications such as extrusion of plastics in the manufacture of Rayon and Nylon, the cooling of reactors, purification of crude oil, textile industry, polymer technology, metallurgy, geothermal engineering, liquid metals and plasma flows, boundary layer control in aerodynamics and crystal growth etc. Nanofluid is envisioned to describe a fluid in which nanometer-sized particles are suspended in conventional heat transfer base fluids to improve their thermal physical properties. Nanoparticles are made from various materials, such as metals (Cu, Ag, Au, Al, Fe), oxide ceramics (Al2O3, CuO, TiO2), nitride ceramics (AlN, SiN), carbide ceramics (SiC, tiC), semiconductors, carbon nanotubes and composite materials such as alloyed nanoparticles or nanoparticle core–polymer shell composites. It is well known that, conventional heat transfer fluids, such as oil, water, and ethylene glycol, in general, have poor heat transfer properties compared to those of most solids. Nanofluids have enhanced thermophysical properties such as thermal conductivity; thermal diffusivity, viscosity and convective heat transfer coefficients compared with those of base fluids like oil or water. Owing to their enhanced properties, nanofluids can be used in a plethora of technical and biomedical applications such as nanofluid coolant: electronics cooling, vehicle cooling, transformer cooling, computers cooling and electronic devices cooling; medical applications: magnetic drug targeting, cancer therapy and safer surgery by cooling; process industries; materials and chemicals: detergency, food and drink, oil and gas, paper and printing and textiles.

Abstract:
Le champ magnétique terrestre et le taux de rotation de la Terre changent sur des périodes de plusieurs années.Dans cette thèse, on cherche à savoir si et comment de tels changements peuvent être causés par des modes (ondes stationnaires) dans le noyau liquide et conducte.Pour ce faire, un modèle de noyau planétaire en rotation rapide et électriquement conducteur est développé, capable de gérer des champs magnétiques complexes et une frontière non sphérique.Nous exploitons la rotation rapide pour simplifier notre modèle, en utilisant l'hypothèse dite quasi-géostrophique, où les composantes horizontales de la vitesse deviennent invariantes le long de l'axe de rotation.En dérivant un tel modèle dans une géométrie non axisymétrique, nous sommes en mesure d'étudier le couple de pression exercé sur la limite noyau-manteau par des modes, qui sont des solutions linéaires au modèle.Les modes d'Alfvén dits de torsion sont particulièrement intéressants, car ils consistent en des cylindres géostrophiques en rotation différentielle les uns par rapport aux autres, potentiellement porteurs d'un moment angulaire axial.Ces cylindres agissent contre la tension des lignes de champ magnétique radiales cisaillées, ce qui montre leur nature Alfvénique.Dans le noyau terrestre, on suppose qu'ils ont des périodes de quelques années et on les a corrélés aux changements de la longueur du jour.Nos résultats suggèrent que le couple de pression associé à de tels modes de torsion Alfvén est inefficace pour expliquer les changements observés dans la longueur du jour terrestre sur des périodes d'environ 6 ans.Il s'avère que l'amplitude de la pression associée à ces modes devrait être indépendante de la vitesse de rotation, si le volume ne permet pas de prendre en compte les contours géostrophiques non fermés.Il convient d'étudier si le couple de pression peut être augmenté en considérant des géométries plus complexes que l'ellipsoïde, considéré ici.Sinon, les modes de torsion Alfvén dans le noyau doivent être couplés à une couche électriquement conductrice dans le manteau inférieur ou par couplage gravitationnel pour expliquer les changements observés dans la longueur du jour.Dans une deuxième partie, nous avons étudié les modes de Magneto-Coriolis dans un modèle de noyau sphérique et homogène, où nous pouvons exprimer le champ magnétique de manière à pouvoir calculer les changements de champ magnétique à la surface du noyau.Sur Terre, les observations du champ géomagnétique à la surface révèlent des changements du champ magnétique à différentes échelles de temps, allant de plusieurs millions d'années à des changements interannuels.En projetant les observations à travers le manteau, les changements interannuels du champ magnétique à la surface du noyau sont interprétés comme le résultat d’une magnétohydrodynamique simple dans le noyau externe liquide.Dans notre modèle, nous calculons les modes de Magneto-Coriolis de périodes de plusieurs années.Ces modes de Magneto-Coriolis rapides montrent une forte focalisation de leur énergie cinétique et magnétique dans la région équatoriale, tout en maintenant une structure spatiale relativement importante le long de la direction azimutale.Leurs propriétés concordent avec certaines propriétés des observations magnétiques et des mouvements à la surface du noyau récemment proposés.De plus, contrairement à ce qui a été supposé précédemment, nous constatons que ces modes ne sont pas affectés de manière significative par la diffusion magnétique.Le nouveau modèle ouvre une nouvelle façon d'inverser les observations géomagnétiques pour en déduire les mouvements et le champ magnétique dans les profondeurs du noyau externe de la Terre
Earth's magnetic field and rotation rate change on periods of several years.In this thesis it is investigated if and how such changes can be caused by modes (standing waves) in the liquid and conducting core.To do so, a model for a rapidly rotating and electrically conducting planetary core is developed that is able to handle non-idealized magnetic fields and a non-spherical boundary.We exploit the rapid rotation of the fluid to simplify our model, using the so-called quasi-geostrophic assumption, where the horizontal components of the velocity become invariant along the axis of rotation.By deriving such a model in a non-axisymmetric geometry, we are able to investigate the pressure torque exerted onto the core-mantle boundary by modes, which are linear solutions to the model.So-called torsional Alfvén modes are of particular interest, as they consist of differentially rotating geostrophic cylinders, potentially carrying axial angular momentum.These cylinders act against the tension of sheared radial magnetic field lines, showing their Alfvénic nature.In Earth's core they are assumed to have periods of a few years and they have been correlated to changes in the length of day on periods of about 6 yr.Our results suggest that the pressure torque associated to such torsional Alfvén modes is inefficient to explain the observed changes in Earth's length of day

A numerical study of flow and heat transfer from boundary layer flow driven by a stretching impermeable plate is proposed. The flow with electrically Newtonian fluid due to the continuous stretching sheet in the presence of a transverse uniform magnetic field was molded as an unsteady, viscous, and incompressible, taking into account the variation of fluid viscosity and thermal conductivity and including the effects of Ohmic heating due to electromagnetic work in the energy equation. The effects of viscous dissipation are neglected in heat flow process. The fluid viscosity is assumed to vary as an inverse linear function of temperature and the thermal conductivity is variable and considered to vary as a linear function of temperature. Similarity analysis with Chebyshev finite difference method (ChFD) was developed to solve the governing equations for mass, momentum and energy. Two different cases are considered, one corresponding to a infinite fluid medium surrounding the stretching sheet and the other, a finite fluid medium, i.e. thin liquid film on a stretching sheet. Graphical results for the effects of various parameters on the fluid velocity and temperature and the skin-friction coefficient and heat transfer rate are presented and discussed. Numerical results showed, for a given unsteadiness parameter, that the local heat transfer rate increases as Prandtl number increase, while it decreases as magnetic field strength, thermal conductivity parameter and viscosity parameter increase. The skin friction, for a given unsteadiness parameter, increases as magnetic field strength and viscosity parameter increase. The film thickness increases with the decreasing in unsteadiness parameter, magnetic field strength, and viscosity parameter in liquid film case. The free-surface temperature decreases with the increasing in unsteadiness parameter, magnetic field strength, Eckert number and viscosity parameter in liquid film case.

A linear stability analysis has been implemented for hydromagnetic flow, a viscous electrically conducting fluid between rotating concentric cylinders in the presence of a uniform axial magnetic field. The small gap equations with respect to three-dimensional disturbances of both axisymmetric and non-axisymmetric are derived and solved by a direct numerical procedure. Both of the two different types of boundary conditions, ideal conducting and non-conducting(or weakly conducting)walls are considered. Results are reported for the following three typical cases: (1)Hydromagnetic stability of dissipative Couette flow: Results show that the stability charqcteristics depend on the conductivity of the cylinders. (2)Hydromagnetic stability of current-induced flow between concentric cylinders: This flow is driven electromagnetically by the interaction of a superimposed radial current and a uniform axial magnetic field. (3)Hydromagnetic stability of current-induced flow between concentric rotating cylinders: The stability analysis of this flow is extended to the case where the primary flow includes a pressure gradient acting in the azimuthal direction. Results are reported for both weakly and ideal conducting cylinders.

Thesis (Ph.D. (Applied Mathematics)) -- University of Limpopo, 2020
The flow of electrically conducting fluids in the presence of a magnetic field has wide applications in science, engineering and technology. Examples of the applications include industrial processes such as the cooling of reactors, extrusion of plastics, purification of crude oil, medical applications, aerodynamics and many more. The induced magnetic field usually act as a flow control mechanism, especially under intense heat. In this study a couple stress fluid in a channel will be used as the working fluid. Channel flow and heat transfer characteristics of couple stress fluids find applications in processes such as the extrusion of polymer fluids, solidification of liquid crystals, cooling of metallic plates in a bath, tribology of thrust bearings and lubrication of engine rod bearings. One major characteristic that distinguishes the couple stress fluid from other non-Newtonian fluids is the inclusion of size-dependent microstructure that is of mechanical significance. As such, the couple stress constitutive model is capable of describing the couple stresses, the effect of body couples and the nonsymmetric tensors manifested in several real fluids of technological importance. A fully developed laminar magnetohydrodynamic (MHD) flow of an incompressible couple stress fluid through a vertical channel due to a steady-periodic temperature on the channel plates is investigated. Specifically, the effects of couple stresses and internal heat generation on MHD natural convection flow with steady-periodic heat input, the impact of magnetic field induction on the buoyancy-induced oscillatory flow of couple stress fluid with varying heating and a mixed convective two dimensional flow of unsteady MHD couple stress fluid through a channel field with porous medium are studied. Analytical methods and the semi-analytic Adomian decomposition method will be used to solve the resulting non-linear differential equations governing the flow systems. Useful results for velocity, temperature, skin friction and Nusselt number are obtained and discussed quantitatively. The effects of the various flow governing parameters on the flow field are investigated.

Based on the thermodynamics second low, this thesis aims to analyze the entropy generation in a fully developed laminar flow of conducting liquid inside a channel that is made of two inclined parallel uniformly heated plates under the action of a transverse magnetic field. The effect of heat generation by viscous dissipation is included in the analysis. According to Adrian Bejan EMG (entropy generation minimization) technique , the dependence of local entropy generation on Hartman number Ha, Brinkman number Br and viscous dissipation parameter BrΩ-1 are discussed numerically. This article observes that entropy generation increases as the value of Harman number, Brinkman number and viscous dissipation parameter increase.

The unsteady hydromagnetic chemically reacting mixed convection MHD ow over a permeable stretching sheet embedded in a porous medium with thermal radiation and heat source/sink is investigated numerically. The original partial di erential equations are converted into ordinary di erential equations by using similarity transformation. The governing non-linear partial di erential equations of Momentum, Energy, and Concentration are considered in this study. The e ects of various physical parameters on the velocity, temperature, and species concentration have been discussed. The parameters include the Prandtl number (Pr), Magnetic parameter (M), the Schmidt number (Sc), Unsteady parameter (A), buoyancy forces ratio parameter (N), Chemical reaction (K), Radiation parameter (Nr), Eckert number (Ec), local heat source/sink parameter (Q) and buoyancy parameter due to temperature ( ). The coe cient of Skin friction and Heat transfer are investigated. The coupled non-linear partial di erential equations governing the ow eld have been solved numerically using the Spectral Relaxation Method (SRM). The results that are obtained in this study are then presented in tabular forms and on graphs and the observations are discussed.

Abstract:
The steady axisymmetric hydromagnetic flow of an incompressible viscous electrically conducting fluid impinging on a porous flat plate with heat transfer are investigated. An external uniform magnetic field and a uniform suction or injection are applied normal to the plate which is maintained at a constant temperature. Numerical solution for the governing nonlinear equations is obtained.

Abstract:
Stability of the magnetorheological rotational flow in the presence of a magnetic excitation in the tangential direction is examined. The conservation of mass and momentum equations for an isothermal Carreau fluid between coaxial cylinders are numerically solved while mixed boundary conditions are assumed. In the absence of magnetic excitation, the base flow loses its radial flow stability to the vortex structure at a critical Taylor number. The emergence of the vortices corresponds to the onset of a supercritical bifurcation. The Taylor vortices, in turn, lose their stability as the Taylor number reaches a second critical number corresponding to the onset of a Hopf bifurcation. The tangential magnetic field turns out to be a controlling parameter as it alters the critical points throughout the bifurcation diagram. Also, the effect of the Hartmann number, the Deborah number and the fluid elasticity on the flow parameters were investigated.

Abstract:
The combined effects of applied magnetic field, thermal radiation and suction on the flow and free convective heat transfer of a viscous, incompressible, electrically conducting dusty fluid past a flat plate with ramped temperature are studied. The governing partial differential equations for momentum and energy transfers, for both the fluid and particle phases, are solved using Laplace transform technique. The inverse Laplace transform is obtained numerically using Matlab. A comparison of Numerical solution and analytical solution for energy transfer is made which shows an excellent agreement. The effects of pertinent flow parameters are analyzed with the help of graphs and tables.
