This book was released on 2013-04-09 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetohydrodynamics is concerned with the motion of electrically conducting fluids in the presence of electric or magnetic fields. Un fortunately, the subject has a rather poorly developed experimental basis and because of the difficulties inherent in carrying out controlled laboratory experiments, the theoretical developments, in large measure, have been concerned with finding solutions to rather idealized problems. This lack of experimental basis need not become, however, a multi megohm impedance in the line of progress in the development of a satisfactory scientific theory. While it is true that ultimately a scientific theory must agree with and, in actuality, predict physical phenomena with a reasonable degree of accuracy, such a theory must be sanctioned by its mathematical validity and consistency. Physical phenomena may be expressed precisely and quite comprehensively through the use of differential equations, and the equations formulated by LUNDQUIST and discussed by FRIEDRICHS belong to a class of equations particularly well-understood and extensively studied. This class includes, in fact, many other eminent members, the solutions of which have led to results of far-reaching scientific and technological application. Frequently, the mathematical analysis has provided the foundations and guidance necessary for further developments, and, reciprocally, the physical problems have provided, in many cases, the impetus for the development of new mathematical theories which often have evolved to an a priori unpredictable extent.

Book Synopsis Numerical Study of 3D Magnetohydrodynamic Flows Towards Liquid Metal Blankets, Including Complex Geometry and Buoyancy Effects by : Tyler James Rhodes
Download or read book Numerical Study of 3D Magnetohydrodynamic Flows Towards Liquid Metal Blankets, Including Complex Geometry and Buoyancy Effects written by Tyler James Rhodes and published by . This book was released on 2019 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding magnetohydrodynamic (MHD) phenomena associated with complex duct geometries and buoyancy effects is required to effectively design liquid metal (LM) blankets for fusion reactors. These topics are investigated in the present work by numerically simulating 3D LM MHD flow using HIMAG (HyPerComp Incompressible MHD solver for Arbitrary Geometry), a code developed by HyPerComp with support from UCLA. In Part I of this dissertation, the simulated geometry is a manifold consisting of a rectangular feeding duct which abruptly expands along the applied magnetic field direction to distribute LM into several parallel channels. As a first step in qualifying the flow, a magnitude of the curl of the induced Lorentz force is used to distinguish between inviscid, irrotational core flows and boundary and internal shear layers where inertia and/or viscous forces are important. Scaling laws are obtained which characterize the 3D MHD pressure drop and flow balancing as a function of the flow parameters and the manifold geometry. Associated Hartmann (Ha) and Reynolds (Re) numbers in the computations are ~10^3 and ~10^1-10^3 respectively while the expansion ratio is varied from 4 to 12. An accurate model for the pressure drop is developed for the first time for inertial-electromagnetic and viscous-electromagnetic regimes based on 96 computed cases. Analysis shows that increasing the distance between the manifold inlet and the entrances of the parallel channels can improve flow balance by utilizing the effect of flow transitioning to a quasi-two-dimensional state in the expansion region of the manifold. Lastly, a Resistor Network Model is developed to describe the effect of the length of the poloidal channels on flow balancing in LM manifold. As the poloidal channels lengthen, the flow balance improves. The simulated geometry in Part II consists of a straight, vertical duct which runs perpendicular to a strong, fringing applied magnetic field. There is also a region of applied heating as the primary goal of Part II is to explore buoyancy effects in MHD duct flows. The unsteady 3D MHD equations are solved using HIMAG. Results are presented for both upwards and downwards flows in electrically conducting (wall conductance ratio cw=0.12) and nonconducting ducts for a range of Ha~10^2, Re~10^3-10^4, and Grashof (Gr) numbers~10^7-10^8. While increasing Gr or decreasing Re increases buoyancy effects, increasing Ha was shown to increase maximum temperature by enhancing flow stability. The extent to which the flow is quasi-2D is analyzed and buoyant effects, in competition with Joule dissipation, are shown to bring about 3D flow features and newly discovered MHD mixed convection phenomena. Steeply diminishing volumetric heating, which approximates nuclear heating, is applied to the vertical MHD flows for comparison to flows with surface heating only. Surface heating generates stronger buoyancy effects than volumetric heating of the same total power; however, many of the same phenomena occur. Therefore, surface heating, the only option for lab experiments, can be useful in exploring the effects of volumetric heating in MHD flows. Lastly, the results of a surface heating case are presented for the purpose of comparison with other codes and experiments, especially the MaPLE-U experiment that is currently is underway at UCLA.
Book Synopsis Effects of a Magnetic Field on the Hypervelocity Flow about a Blunt Body by : Richard W. Ziemer
Download or read book Effects of a Magnetic Field on the Hypervelocity Flow about a Blunt Body written by Richard W. Ziemer and published by . This book was released on 1958 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was made of the effect of an applied magnetic field on the bow shock of a blunt body in hypervelocity air flow. Quantitative measurements of the stand-off distance were made in a three-inch electromagnetic shock tube with free-stream velocities up to 22,000 feet per second. The test body was a hemispherical cylinder containing a coaxial pulsed magnet coil in the nose which produced field strengths at the stagnation point of up to 40 kilogauss. The application of the magnetic field displaced the bow shock upstream and the stand-off distance increased by a factor of 7.5 for the condition, nondimensional parameter = 69. The experimental results were compared with theory and good agreement was obtained within the range of experimental conditions. (Author).

Book Synopsis Magnetohydrodynamics of Plasma Relaxation by : S. Ortolani
Download or read book Magnetohydrodynamics of Plasma Relaxation written by S. Ortolani and published by World Scientific. This book was released on 1993 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a concise description of the phenomenon of plasma relaxation from the point of view of resistive magnetohydrodynamic (MHD) theory. Magnetized plasmas relax when they seek their natural state of lowest energy subject to certain topological constraints imposed by the magnetic field. Relaxation may be fast and dynamic or slow and gradual depending on the external environment in which the magnetoplasma system evolves. Relaxation occurs throughout the universe and may describe such diverse phenomena as dynamos, solar flares, and the operation of magnetic fusion energy experiments. This book concentrates on the dynamic, rather than variational aspects of relaxation. While the processes described are general, the book focuses on the reversed-field pinch experiment as a paradigm for plasma relaxation and dynamo action. Examples from other branches of plasma physics are also discussed. The authors draw upon their extensive experience in numerical and experimental studies of relaxation.
Book Synopsis Heat and Mass Transfer in MHD Flows by : Elm?rs Bl?ms
Download or read book Heat and Mass Transfer in MHD Flows written by Elm?rs Bl?ms and published by World Scientific. This book was released on 1987 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of heat and mass transfer processes by means of external force effects is one of the most important problems in modern applied physics. This book is devoted to the study of the magnetic field effect as it bears on transfer phenomena: heat and mass transfer. In conducting media, this influence is mainly due to the induced electric current and the interaction of the current with the magnetic field, whereas in magnetizable fluids, molecular or colloidal solution, transfer phenomena are directly affected by the field. When analysing heat and mass transfer in multiphase magnetizing media, only those phenomena which could be described in terms of conventional quasi-stationary approximation are considered. The effects assoicated with the non-equilibrium magnetization of the system and particle interaction receive special attention here. The problem studied here have been considered with a view to possible applications, particularly in biology and medicine.

Available in PDF, EPUB and Kindle. Book excerpt: Liquid metal MHO is within the scope of two series of international conferences. One is the International Congress on "MHD Power Generation", held every four years, which includes technical and economical aspects as well as scientific questions. The other if the Beer-Sheva Seminar on "MHO Flows and Turbulence", held every three years in Israel. In addition to these well established meetings, an IUTAM Symposium was previously organized in Cambridge (UK) in 1982 on "Metallurgical Applications of MHD" by the late Arthur Shercliff. It was focussed on a very specific subject developing radiply from the middle of the 1970's. The magnetic field was generally AC, including frequencies high enough for the skin-depth to be much smaller than the typical length scale of the liquide pool. And the development of new technologies, or the improvement of existing ones, was the main justification of most of the researches presented and discussed. Only two participants from Eastern countries attended this Symposium. By the middle of the 1980's we felt that on this very same topic ideas had reached much more maturity than in 1982. We also realized that a line of research on MHD flows related to fusion reactors (tokamaks) was developing significantly, with particular emphasis on flows at large interaction parameter.
