Book excerpt: The basic equations and some fundamental concepts of magnetoaerodynamics are discussed. As an application, the problem of the flow near the stagnation point of a body of revolution is reviewed and an exact solution is given. Data are presented for the heat transfer coefficient at the stagnation point, and for its gradient in the stagnation point region. The magnetic field strength required to accomplish an appreciable reduction of aerodynamic heating in hypersonic flight is discussed, for the case in which ionization is due to thermal motion. Alternatively, methods which involve electrical breakdown of the air are considered.

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.

Download or read book Thermodynamic Cycle Analysis of Magnetohydrodynamic-bypass Hypersonic Airbreathing Engines written by R. J. Litchford and published by . This book was released on 2000 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prospects for realizing a magnetohydrodynamic (MHD) bypass hypersonic airbreathing engine are examined from the standpoint of fundamental thermodynamic feasibility. The MHD-bypass engine, first proposed as part of the Russian AJAX vehicle concept, is based on the idea of redistributing energy between various stages of the propulsion system flow train. The system uses an MHD generator to extract a portion of the aerodynamic heating energy from the inlet and an MHD accelerator to reintroduce this power as kinetic energy in the exhaust stream. In this way, the combustor entrance Mach number can be limited to a specified value even as the flight Mach number increases. Thus, the fuel and air can be efficiently mixed and burned within a practical combustor length, and the flight Mach number operating envelope can be extended. In this paper, we quantitatively assess the performance potential and scientific feasibility of MHD-bypass engines using a simplified thermodynamic analysis. This cycle analysis, based on a thermally and calorically perfect gas, incoporates a coupled MHD generator-accelerator system and accounts for aerodynamic losses and thermodynamic process efficiencies in the various engine components. It is found that the flight Mach number range can be significantly extended; however, overall performance is hampered by non-isentropic losses in the MHD devices.

Download or read book Thermal and Solutal Convection in Some Hydromagnetic Flows written by Nazibuddin Ahmed and published by Springer Nature. This book was released on 2023-01-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a theoretical analysis of several problems in thermal and solutal convections in magneto-hydrodynamic (MHD) flows. It provides a systemic discussion on the development of fluid dynamics, continuum hypothesis, Newton’s law of viscosity, heat transfer, mass transfer, thermal diffusion, diffusion-thermo-MHD, gray and non-gray gases, Fourier’s law of conduction, and Fick’s law of diffusion in such a way that readers with little knowledge in physics will find it easier to understand the contents. Some physical principles, such as those governing fluid motion, fluid temperature, and fluid concentration, are presented in vector form, allowing the corresponding form to be derived in any orthogonal curvilinear coordinate system. Laplace transform technique in closed form is used to obtain exact solutions to unsteady one-dimensional flow problems, an implicit finite difference method of Crank–Nicholson type is used to solve unsteady two-dimensional flow problems, and an asymptotic series expansion method is used to solve the governing equations of the steady three-dimensional flow problem analytically. Flow and transport phenomena are thoroughly treated in each chapter separately. This book emphasizes the influence of an induced magnetic field. The outcomes of the works are graphically depicted so that readers can gain a tangible understanding of the problems. It also includes a list of inverse Laplace transforms (ILTs) for several specific functions, some of which are not found in the existing literature. The ILTs of special functions are given in brief form and can further be utilized as standard formulae in finding those as special cases. Some new special functions are introduced in the book, along with appropriate definitions. As a result, the formulations for velocity, temperature, concentration, skin friction, Nusselt number, and Sherwood number have been appeared in brief and convenient forms that are uncommon in other literature. This book addresses numerous areas of contemporary magneto-fluid dynamics research that have major implications in engineering. It is primarily intended for researchers working in the field of heat and mass transfer in hydromagnetic flows.

Book excerpt: An experimental investigation was conducted at a test-section Mach number of 4.95 and a stagnation temperature of 400 F to evaluate a visual technique for obtaining qualitative aerodynamic heat-transfer data on complex configurations.This technique utilized a temperature-sensetive paint indicated that this technique was satisfactory for determining qualitative heat-transfer rates on various bodies, some of which exhibited complex flow patterns. The results obtained have been found useful to guide the instrumentation of quantitative heat-transfer models, to supplement quantitative heat-transfer measurements, and to make preliminary heat-transfer studies for new configurations.

Available in PDF, EPUB and Kindle. Book excerpt: To understand plasma physics intuitively one need to master the MHD behaviors. As sciences advance, gap between published textbooks and cutting-edge researches gradually develops. Connection from textbook knowledge to up-to-dated research results can often be tough. Review articles can help. This book contains eight topical review papers on MHD. For magnetically confined fusion one can find toroidal MHD theory for tokamaks, magnetic relaxation process in spheromaks, and the formation and stability of field-reversed configuration. In space plasma physics one can get solar spicules and X-ray jets physics, as well as general sub-fluid theory. For numerical methods one can find the implicit numerical methods for resistive MHD and the boundary control formalism. For low temperature plasma physics one can read theory for Newtonian and non-Newtonian fluids etc.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of nozzle nonequilibrium in a high temperature, hypersonic test facility were evaluated. By using the results of a set of exact computer solutions for air nozzle expansions to interpolate frozen atomic mole fraction and the fraction of total enthalpy frozen in dissociation and vibration, a method was devised for direct determination of (1) freestream quantities downstream of the freezing region in a nonequilibrium nozzle expansion, (2) the nozzle boundary layer growth, and (3) the aerodynamic effects of freestream nonequilibrium. The freestream results are shown to compare favorably with exact computer solutions. Illustrative applications to hypersonic inlet testing and downstream expansion following an MHD accelerator are included. (Author).
