▼ In this thesis, we simulate the flow of an electrically conducting fluid past an obstacle placed inside a duct under the influence of an externally applied magnetic field. Three different obstacles are considered: a circular and a square cylinder spanning over the full height of the duct and a square cylinder spanning over the half height of the duct. The magnetic field is oriented along the cylinder axis and the duct is electrically insulating. In a first stage of the thesis, we perform a parametric study over both Ha and Re in the case where both Ha ≫ 1and N ≫ 1 with 2D simulations using the quasi-2D flow model by [165]. In particular, we provide the first explanation of the collapse of the regular Kármán vortex street observed experimentally by [180]. We also derive two different scaling laws linking the evolutions of the flow coefficients and either Re/Ha or Re/Ha0.8. The second phase of the thesis is dedicated to the development of a 3D MHD capable code to solve the flow equations with the inductionless approximation. This code is used to investigate the 3D MHD flow past a truncated square cylinder in a duct. We explain the different stages of elaboration of our code and validate its performances to MHD duct flows and cylinder wakes. We also implement a wall function at the interface between the Hartmann layers and the bulk flow. The non-MHD flow past the truncated cylinder is simulated for 10 ≤ Re ≤ 400. In particular, the early stages of the unsteady flow regime is characterised by a regular symmetric procession of hairpin vortices. We explain the formation mechanism of these vortices and its evolution when Re is increased. Finally, we investigate the MHD flow past the electrically insulating truncated cylinder at Ha=100 and 200 for Re up to 1000. The flow dynamics is strongly 2D with the presence of a Hunt’s wake at very low Re. The unsteady regime leads to the development of a Kármán vortex street. Switching to a perfectly conducting truncated square cylinder enhances the braking of the flow by the Lorentz force in the region above the cylinder tip.

▼ Magnetic reconnection in plasmas, a process characterized by a change in connectivity of field lines that are broken and connected to other ones with different topology, owes its usefulness to its ability to unify a wide range of phenomena within a single universal principle. There are newly observed phenomena in the solar corona that cannot be reconciled with two-dimensional or steady-state standard models of magnetic reconnection. Supra-arcade downflows (SADs) and supra-arcade downflowing loops (SADLs) descending from reconnection regions toward solar post-flare arcades seem to be two different observational signatures of retracting, isolated reconnected flux tubes with irreducible three-dimensional geometries. This dissertation describes work in refining and improving a novel model of patchy reconnection, where only a small bundle of field lines is reconnected across a current sheet (magnetic discontinuity) and forms a reconnected thin flux tube. Traditional models have not been able to explain why some of the observed SADs appear to be hot and relatively devoid of plasma. The present work shows that plasma depletion naturally occurs in flux tubes that are reconnected across nonuniform current sheets and slide trough regions of decreasing magnetic field magnitude. Moreover, through a detailed theoretical analysis of generalized thin flux tube equations, we show that the addition to the model of pressure-driven parallel dynamics, as well as temperature-dependent, anisotropic viscosity and thermal conductivity is essential for self-consistently producing gas-dynamic shocks inside reconnected tubes that heat and compress plasma to observed temperatures and densities. The shock thickness can be as long as the entire tube and heat can be conducted along tube's legs, possibly driving chromospheric evaporation. We developed a computer program that solves numerically the thin flux tube equations that govern the retraction of reconnected tubes. Simulations carried out with this program corroborate our theoretical predictions. A comparison of these simulations with fully three-dimensional magnetohydrodynamic simulations is presented to assess the validity of the thin flux tube model. We also present an observational method based on total emission measure and mean temperature to determine where in the current sheet a tube was reconnected.

▼ We present the results of three proposed mechanisms for ejection of gas from a spiral arm into the halo. The mechanisms were modelled using magnetohydrodynamics (MHD) as a theoretical template. Each mechanism was run through simulations using a Fortran code: ZEUS-3D, an MHD equation solver. The first mechanism modelled the gas dynamics with a modified Hartmann flow which describes the fluid flow between two parallel plates. We initialized the problem based on observation of lagging halos; that is, that the rotational velocity falls to a zero at some height above the plane of the disk. When adopting a density profile which takes into account the various warm and cold H_I and H_II molecular clouds, the system evolves very strangely and does not reproduce the steady velocity gradient observed in edge-on galaxies. This density profile, adopted from Martos and Cox (1998), was used in the remaining models. However, when treating a system with a uniform density profile, a stable simulation can result. Next we considered supernova (SN) blasts as a possible mechanism for gas ejection. While a single SN was shown to be insufficient to promote vertical gas structures from the disk, multiple SN explosions proved to be enough to promote gas ejection from the disk. In these simulations, gas ejected to a height of 0.5 kpc at a velocity of 130 km s^-1 from 500 supernovae, extending to an approximate maximum height of 1 kpc at a velocity of 6.7 × 10³ km s^-1 from 1500 supernovae after 0.15 Myr, the approximate time of propagation of a supernova shock wave. Finally, we simulated gas flowing into the spiral arm at such a speed to promote a jump in the disk gas, termed a hydraulic jump. The height of the jump was found to be slightly less than a kiloparsec with a flow velocity of 41 km s^-1 into the halo after 167 Myr. The latter models proved to be effective mechanisms through which gas is ejected from the disk whereas the Hartmann flow (or toy model) mechanism remains unclear as the heliocentric velocity profile becomes unstable when run through a time-dependent simulation. Though the cause of this instability is unclear, pressure fluctuations in the system are suspected to play a role.

▼ The present study is concerned with the stability of a flow of viscous conducting liquid driven by a pressure gradient between two parallel walls in the presence of a transverse magnetic field, which is investigated using a Chebyshev collocation method. This magnetohydrodynamic counterpart of the classic plane Poiseuille flow is generally known as Hartmann flow. Although the magnetic field has a strong stabilizing effect, the turbulence is known to set in this flow similarly to its hydrodynamic counterpart well below the threshold predicted by the linear stability theory. Such a nonlinear transition to turbulence is thought to be mediated by unstable equilibrium flow states which may exist in addition to the base flow. Firstly, the weakly nonlinear stability analysis carried out in this study shows that Hartmann flow is subcritically unstable to small finite-amplitude disturbances regardless of the magnetic field strength. Secondly, two-dimensional nonlinear travelling wave states are found to exist in Hartmann flow at substantially subcritical Reynolds numbers starting from Ren = 2939 without the magnetic field and from Ren ∼ 6.50 × 103Ha in a sufficiently strong magnetic field defined by the Hartmann number Ha. Although the latter value is by a factor of seven lower than the linear stability threshold Rel ∼ 4.83×104Ha and by almost a factor of two lower than the value predicted by the mean-field (monoharmonic) approximation, it is still more than an order of magnitude higher than the experimentally observed value for the onset of turbulence in this flow. Three-dimensional disturbances are expected to bifurcate from these two-dimensional travelling waves or infinity and to extend to significantly lower Reynolds numbers. The by-product of this study are two developments of numerical techniques for linear and weakly nonlinear stability analysis. Firstly, a simple technique for avoiding spurious eigenvalues is developed for the solution of the Orr-Sommerfeld equation. Secondly, an efficient numerical method for evaluating Landau coefficients which describe small amplitude states in the vicinity of the linear stability threshold is introduced. The method differs from the standard approach by applying the solvability condition to the discretised rather than the continuous problem.

▼ The liquid metal battery (LMB) has already emerged out of the lab bench and into commercial deployment for grid-scale energy storage. However, there are still various engineering challenges that need to be solved in order to improve the LMB’s ability to supply energy at lower cost. This thesis will focus on overcoming the challenges of high operating temperature and mass transport kinetic losses. To address the problem of high operating temperature, a rigorous experimental research program was undertaken. The feasibility of low and intermediate temperature electrolytes for sodium based liquid metal batteries operating at temperatures below 300 °C was investigated. First, the binary NaOH, NaI electrolyte was studied by building and cycling Na|Bi LMBs at temperatures below 280 °C. Side reactions leading to capacity fade were identified and their free energies were calculated. Second, the electrochemical feasibility of a novel ternary NaNH2, NaOH, NaI electrolyte for Na|PbBi LMBs was investigated using a three-electrode setup. Cycling voltammetry was used to measure an electrochemical window of 1.3V at 180 °C. Thermodynamic calculations were used to determine the limiting oxidation reaction. A second three-electrode setup that employs Na in β"-Al2O3 as a reference electrode, eutectic Bi-Pb working electrodes and a Na-Bi- Pb counter electrode was used to investigate the optimal operating conditions for a Na|PbBi LMB. PbBi electrodes were discharged to a predetermined molar concentration of Na and cross-sectioned. Samples were analyzed using energy dispersive x-ray spectroscopy and scanning electron microscopy. To understand the fundamentals of mass transport in LMBs, a comprehensive experimental model was developed to investigate the flow in PbBi electrodes operating at a temperature between 160 and 180 °C. Ultrasound Doppler Velocimetry (UDV) was used to measure the flow in shallow PbBi electrodes at current densities ranging from 0 to 640 mA/cm2. We identified two competing flow phenomena, namely, thermal convection and electro-vortex flow. A simple dimensionless ratio was also developed to predict their relative strength. The same setup was also used to study the impact of electrical connection and current topology on the emergence of swirling flow in LMBs. Stray axial fields from nearby wires or even that of the earth were found to cause tornado-like flows in shallow PbBi electrodes. The engineering ramifications and design implications of the experimental results are also discussed. The last part of this thesis serves as an engineering application for the result of our experimental models. A two-dimensional convection-diffusion model was developed to quantify the effect fluid flow on the performance of LMBs. Using a two dimensional stream function to represent thermal convection, we solved the convection-diffusion equation for Li+ in Bi. Using the obtained concentration profiles, we determined the voltage drop due to the accumulation of Li+ products at the interface. Increasing flow speed was…

▼ Accreting magnetized stars are ubiquitous throughout astrophysics and can be found in a variety of astrophysical contexts at both the dawning and closing stages of stellar evolution. These include the young stars at the center of T Tauri-type systems, accreting white dwarfs in cataclysmic variables as well as neutron stars found in low-mass X-ray binaries. The interaction between these stars and their accretion discs is a process which is fundamental to astrophysics: of particular importance is the disc-magnetosphere interaction which determines many of the spectral and time-variable photometric signatures observed in these systems. However, direct imaging of the disc-magnetosphere boundary is observationally challenging due to current resolution limitations while purely analytical studies are difficult due to the highly non-linear nature of magnetohydrodynamic interactions. Simulations bridge the gap between theory and observation and permit us to model the complex interactions in the inner disc with unprecedented detail. In this work, we present the results of pioneering magnetohydrodynamic (MHD) simulations of accretion, planet migration and outflow phenomena at the discmagnetosphere boundary and in the inner disc. In order to investigate these processes, we have developed scalable, high-resolution Godunov-type MHD codes in 2.5D axisymmetric cylindrical, 2D plane polar, and fully 3D cylindrical coordinates aimed at studying accretion driven by the magnetorotational instability as well as the discmagnetosphere interaction. The codes support the inclusion of a planetary perturber and include modules for [alpha]-type viscosity and diffusivity in the disc. Our MHD simulations have established the occurrence of long-lasting outflows in both slowly and rapidly rotating stars. In the slowly rotating regime where rm [LESS-THAN OR EQUAL TO] rc , a well-collimated outflow is launched from the disc-magnetosphere boundary in regimes where the accretion rate is high and the stellar dipole is strongly compressed. The models show that the matter outflows from the disc-magnetosphere boundary with halfopening angles [theta] = 20[-]30? and is collimated by the toroidal magnetic field such that the opening angle narrows to [theta] = 4 [-] 20? at the edge of the simulation region. The outflow velocities range from 30 km s[-]1 at the outer edge of the jet to more than 260 km s[-]1 in the interior regions. This outflow mechanism may help to explain the spectral features observed in the major accretion events associated with FU Orionis and EX Lupi-type outbursts as well as the powerful bipolar jets observed in T Tauri systems. In the rapidly rotating propeller regime of accretion where the magnetosphere rotates faster than the inner disk, the MHD models show the emergence a matter-dominated magnetocentrifugal outflow driven from the disc-magnetosphere boundary. However, unlike the outflow in slower rotating regime, the propeller outflow is primarily rotationpowered and can launch a large majority of the accreting matter into a wide… Advisors/Committee Members: Lovelace,Richard V E (chair), Stacey,Gordon John (committee member), Diamessis,Peter J.

Evolucija ostataka supernovih vezana je za kretanje jednog, bezsudarnog udarnog talasa, nastalog prilikom prostiranja odbacenog zvezdanog materijala nakon eksplozije supernove, velikom brzinom kroz med-uzvezdanu sredinu. Teorijska razmatranja udarnih talasa su neophodna radi boljeg razumevanja emisionih maglina i, generalno, procesa u med-uzvezdanoj sredini. U okviru ove disertacije, izmed-u ostalog, predstavljeni su rezultati magnetohidrodinamicke (MHD) teorije udarnih talasa sa posebnim osvrtom na moguca resenja u svetlu modela idealne radijativne MHD za opticki gust slucaj. Specijalno, diskutovana su moguca svojstva udarnih talasa kada je dozvoljen skok adijabatskog indeksa i/ili parametra koji odred-uje odnos gasnog prema ukupnom pritisku. Osnovna hipoteza, razmatrana u okviru ove disertacije, odnosi se na mogucnost znacajnog ucesca termalnog zakocnog zracenja u neprekidnom radio-spektru pojedinih Galaktickih ostataka supernovih. Pozitivan odgovor na ovo pitanje bi mogao predstavljati prirodno objasnjenje blago konveksnih neprekidnih radio-spektara pojedinih Galaktickih ostataka koji se prostiru kroz sredinu koja je nesto gusca od prosecne. U tom smislu je vazno utvrditi postojanje indikatora termalnog ansambla elektrona, na dovoljno niskim temperaturama i dovoljno velikim gustinama, kako bi se zakocno zracenje moglo detektovati u radio-podrucju (blizina, interakcija ili prostiranje ostatka kroz molekulski oblak, prisustvo ohlad-enih elektrona koji su ranije zracili u X-podrucju, u fazama nakon Sedov-Tejlorove, detekcija niskofrekventnog krivljenja radio-spektra usled termalne apsorpcije vezane za sam ostatak, detekcija u H, identikacija radio-rekombinacionih linija vezanih za sam ostatak, itd). Znacajno prisustvo termalne komponente u principu moze objasniti i radiospektralne indekse manje od 0.5 odred-ene kod nekolicine evolutivno starijih ostataka (uglavnom mesane morfologije), koji se sire kroz guscu sredinu. Zapravo, u tom slucaju bi manji spektralni indeksi, pod pretpostavkom prostog stepenog zakona, predstavljali prirodnu manifestaciju znacajnog udela termalnog zakocnog zracenja u neprekidnom radio-spektru ostataka supernovih...

▼ Experimental studies of MHD modes, including dynamics and stability, using a biased electrode for rotation control on the High Beta Tokamak –- Extended Pulse (HBT-EP) are presented. When the probe is inserted into the edge of the plasma and a voltage applied, the rotation of long-wavelength kink instabilities is strongly modified. A large poloidal plasma flow results at the edge, measured with a bi-directional Mach probe with changes in edge kink mode rotation at different biases. This poloidal plasma rotation cannot fully account for the large mode rotation frequency on HBT-EP. By including the electron fluid motion, the mode rotation predictions agree with measurements, indicating that the modes travel with the electron fluid. A GPU-based digital feedback system is used to adjust the probe voltage in real time for controlling both the plasma flow and mode rotation. This active mode rotation control is desirable because it allows for MHD stabilization, as well as studies under conditions of varying mode rotation rates. Mode dynamics were studied using various diagnostics to understand how plasma conditions fluctuate during mode activity and to understand the interaction of the bias probe with the plasma during this activity. Phase-dependent mode behavior was observed, especially at slow mode rotation, which might be attributed to an intrinsic error field or a nonlinear interaction between the bias probe and the mode. Applied resonant magnetic perturbations were used to study the dynamic response of a stable plasma with different mode rotations. At slower rotation, the plasma had a greater response to the perturbations and the plasma reached a saturated response with large perturbations, similar to previous results. At large positive biases, the probe current induces a torque that opposes the natural direction of mode rotation. By applying a sufficiently large torque, a transition is induced into a fast rotation state (both mode and plasma rotation). High poloidal shear flows at the edge were measured in this state, similar to conditions in H-mode plasmas on other devices. The bias required to induce the transition is shown to depend on an applied error field. A technique was established using this transition to determine the natural error field on HBT-EP.

▼ The subject of fluid dynamics contains some of the last remaining unsolved challenges in classical physics. In particular, the dynamics of rotating fluids still pose many unanswered questions despite the availability of modern supercomputers. It is often the case that the parameter regimes in which we are interested are those which are the most difficult to reach. It is therefore common to focus on specific aspects of a problem rather than try to solve the complete set of governing equations. In the case of rotating fluid dynamics, one such aspect is that of inertial modes. These are oscillations of the fluid arising solely from the pressure and Coriolis forces in the momentum equation. In a sphere or spherical shell, inertial modes may be excited and maintained by precession of the rotation axis. In the first part of this thesis we shall consider the unforced inertial oscillations in spherical geometry. This simplified approach still gives us slowly decaying inertial modes which we believe will exhibit the same behaviour as their forced counterparts. The motivation for studying this problem is to try to explain the origin of the internal shear layers that are known to exist within the structure of these modes. In the second part of this thesis we move into the realm of Magnetohydrodynamics where the rotating fluid is now treated as an electrical conductor and can therefore conduct currents under the action of electromagnetic fields. Again we focus on one specific area, that of magnetic stability, as opposed to solving the full 3-D dynamo equations. Here we are interested in the stability of axisymmetric magnetic fields (generated via an alpha effect) to nonaxisymmetric perturbations. This analysis will help to determine how strong a field we can expect to find in the liquid iron core of the Earth and if it is possible for that field to equilibrate at lower field strengths than the critical onset value. This may be important in understanding the mechanism of geomagnetic reversals.

▼ Magnetic flux emergence is the subject of how magnetic fields from the solar interior can rise and expand into the atmosphere to produce active regions. It is the link that joins dynamics in the convection zone with dynamics in the atmosphere. In this thesis, we study many aspects of magnetic flux emergence through mathematical modelling and computer simulations. Our primary aim is to understand the key physical processes that lie behind emergence. The first chapter introduces flux emergence and the theoretical framework, magnetohydrodynamics (MHD), that describes it. In the second chapter, we discuss the numerical techniques used to solve the highly non-linear problems that arise from flux emergence. The third chapter summarizes the current literature. In the fourth chapter, we consider how changing the geometry and parameter values of the initial magnetic field can affect the dynamic evolution of the emerging magnetic field. For an initial toroidal magnetic field, it is found that its axis can emerge to the corona if the tube’s initial field strength is large enough. The fifth chapter describes how flux emergence models can produce large-scale solar eruptions. A 2.5D model of the breakout model, using only dynamic flux emergence, fails to produce any large scale eruptions. A 3D model of toroidal emergence with an overlying magnetic field does, however, produce multiple large-scale eruptions and the form of these is related to the breakout model. The sixth chapter is concerned with signatures of flux emergence and how to identify emerging twisted magnetic structures correctly. Here, a flux emergence model produces signatures found in observations. The signatures from the model, however, have different underlying physical mechanisms to the original interpretations of the observations. The thesis concludes with some final thoughts on current trends in theoretical magnetic flux emergence and possible future directions. Advisors/Committee Members: Hood, Alan W (advisor).

▼ The physical processes involved in star formation are not completely understood and are hotly debated in the literature. Star formation occurs in molecular clouds, which are turbulent, dense environments with strong magnetic fields and very low ionization fractions. Early models of star formation relied on strong magnetic fields and ambipolar diffusion to regulate star formation. Later models suggested that turbulence was the primary driver of star formation. More recent models suggest that both could play an important role. Recent observations have shown a difference between ion and neutral line widths in some molecular clouds; specifically, the ion line-widths were narrower than the neutrals. This was attributed to the effect of ambipolar diffusion on the turbulence in the ions. We present high resolution simulations which include the full dynamics of both ions and neutrals. This has only previously been done at relatively low numerical resolutions. This sort of simulation, which tracks the full dynamics of both ions and neutrals, is necessary to reproduce observations that show any difference between ions and neutrals. The results show that the magnetic fields present in molecular clouds influence the velocity and density distributions of the ions and neutrals in a way which would be observable. When viewed with the mean magnetic field in the plane of the sky, the line widths of the ions are preferentially narrower than those of the neutrals. The line widths are nearly the same when viewed along the direction of the magnetic field. The probability distribution functions of the column densities of ions and neutrals are different when observed along the direction of the magnetic field, and they are the same when observed perpendicular to the mean field. Thus, the simulations predict complementary observables each sensitive to different components of the magnetic field. These effects have implications in the observation of magnetic field strengths and could be used to deepen our understanding of the magnetic fields in molecular clouds. The simulations also show that the turbulent cascade in the ions is not damped at the ambipolar diffusion length scale, but continues to smaller length scales depending on the magnetic field strength.
