    Past efforts at modeling laminar, cascade arc behavior are reviewed. The models are delineated in terms of their inherent restrictions and are compared on the basis of ease of application, as well as ability to provide useful engineering information and important physical insights. It is concluded that, although approximate analytical models have suggested important trends, they have almost univer... View full abstract»

    The thermal, flow and electrical conditions are presented for the downstream portion of an argon arc with local fluid constriction. The arc is initially wall-stabilized in a 10 mm diameter water-cooled constrictor and at some point after flow becomes fully developed the arc is constricted by a radial inward jet. The redevelopment of the flow downstream of the injection slot is investigated by meas... View full abstract»

    The constrictor wall heat flux characteristics of a high intensity argon arc with a transpiration cooled constrictor are discussed. An apparatus utilizing a segmented plenum chamber is described which provides in contrast to previous experiments more uniform constrictor wall temperatures. This permits lower total transpirant mass flow rates so that laminar flow within the constrictor tube can be m... View full abstract»

    Some results of an approximate similarity approach are presented applied to electric arc discharges and the underlying basic criteria are delineated. It is shown that the most important process may be specified for each type of discharge from which arc parameters mainly depend on. In addition to the main process, a number of other processes are also involved which exert a weaker influence on the a... View full abstract»

  • Analysis of Cross-Flow Arcs in Transverse Magnetic Fields

    Publication Year: 1973, Page(s):38 - 46
    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1123 KB)

    Through the specification of two independent variables (e. g., arc current and mainstream velocity), and using appropriate phenomenological relations, the flow fields, temperature fields, and arc boundary shapes of magnetically balanced cross-flow arcs have been determined. Flow through the arc occurs at lower Reynolds numbers, Reo ~ 1; at higher Reynolds numbers a dividing streamline is formed, i... View full abstract»

  • Stable Configuration of Electric Arcs in Transverse Magnetic Fields

    Publication Year: 1973, Page(s):47 - 54
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (905 KB)

    Deviations from rotational symmetry of arc columns exposed to transverse magnetic fields cause convection and a momentum transport between the column and its surrounding gas. As a consequence, the arc moves and changes its geometry until it reaches a stable configuration. Based on the momentum transport equation, the arc behavior is discussed under various operating conditions, and stable arc conf... View full abstract»

  • Holographic Interferometry of Arc Discharges Displaced by Magnetic Fields

    The first part of the paper gives a survey of some theoretical aspects of the behavior of a free burning arc in transverse cross-flow and magnetic field. After a short discussion of the variety of forces acting on the arc, the low current case is investigated, in which the external magnetic field is assumed to change aperiodically with time. In the second part, an arc experiment is described which... View full abstract»

    Experiments are reported which allow the determination of retrograde velocity of individual cathode spots and of the plasma flow in a pulsed discharge using various metals and carbon as cathode materials. For discharge currents from 10 to 40 amps, pressures of 3 mmHg and magnetic field strengths of 6.103G retrograde spot velocities from 30 to approximately 300 m/sec are observed and the correspond...

  • Anode Heat Transfer in a DC Electric ARC with Superimposed Axial Flow

    Publication Year: 1973, Page(s):65 - 75
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1215 KB)

    A DC electric arc is operated in argon at pressures between 100 and 760 mm Hg, axial flow velocities from 0 to 100 m/sec, and currents from 50 to 200 amps to assess the influence of these parameters on anode heat transfer using a double-anode configuration consisting of two plane, parallel anodes. Since the anode arc attachment size is appreciably smaller than the anode surface area in these exper... View full abstract»

    This paper deals with the problem of ignition to the porous transpiration cooled anode of an arc in 1 atm. argon. This was observed for both porous graphite and sintered porous tungsten anodes, in the latter case causing melt spots to form which limited the useful life of the anode. A study was undertaken to overcome this problem in which the transient behavior of the arc current, voltage, anode s... View full abstract»

  • An Experimental Study of a Radial Coaxial Gaseous Discharge

    Experimental measurements of a radial coaxial gaseous discharge were made using an adjustable Langmuir probe and a microwave interferometer. Excellent agreement of these results is observed when inhomogeneities of both the electron number density and temperature are accounted for and the electronneutral collisions are assumed to be "hard-sphere" collisions.

    The scope of this research is to investigate experimentally electron (ne), negative ion (n-) and positive ion (n+) densities characterizing laboratory negative ion-rich plasmas, produced by electron attachment in N2O3, O2 and I2, and to find out the factors limiting the achievement of very low ¿¿ (relative electron density ¿¿ = ne/n+). These plasmas may be of great interest for the production of n... View full abstract»

    The radiation patterns of a longitudinal electron plasma wave excited in a warm unbounded plasma by a grid and parallel plane grids and the reception patterns for wire antennas and the grid having a grounded plate were measured experimentally. The results agreed well with theoretically predicted radiation patterns based on a fluid model description for electrons. The dependence of the received amp... View full abstract»

    The MHD generator is presently recognized as one of the more promising new methods of thermal to electric energy conversion and is presently being developed for this purpose, primarily with fossil fuels in mind as the source of heat. However, this "conventional" type of MHD, which uses a "plasma" having greater similarity to the combustion gas in a conventional furnace than to the cloud of kilovol... View full abstract»

  • A Distribution Function for the Particles in an Anisotropic Relativistic Plasma

    Publication Year: 1973, Page(s):108 - 110
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (383 KB)

    The particles making up a plasma are usually not in equilibrium, and their energies are often relativistic and anisotropically distributed, especially if the plasma is in a d.c. magnetic field. Thus, the usual methods for developing particle distribution functions based on equilibrium conditions are not applicable. A development of a particular anisotropic relativistic distribution function that m... View full abstract»
