    Steady, motionless cascaded N2-arcs with tube diameters of 2, 3, and 5 mm are investigated at atmospheric pressure to gain insight into the radiative energy transport for temperatures up to 27,000 K. From the electrical characteristics, the total emitted radiation, and the temperature distributions, the electrical conductivity and the transparent emission are evaluated. It is shown that transparen... View full abstract»

    The lowering of the ionization potentials of hydrogen and carbon atoms immersed in a high temperature and high density thermal plasma generated in a wall stabilized arc have been estimated from the advance or shift of their respective series limits in the vacuum ultraviolet region of the spectrum for different electron densities and temperatures. Results show a close agreement with those theoretic... View full abstract»

    The thermostatic states of a 100 amp, 1.016 bar, free-burning helium short arc with a 10 mm electrode gap are mapped from spectroscopic measurements at eight cross sections. The theoretical model used is a multifluids model extended to consider nonequilibrium between electron and excitation temperatures, as well as simple nonequilibrium among excited electronic levels. Seven helium lines are used ... View full abstract»

    A brief account is given of ideas which are aimed at providing a common reference point for theoretical treatments of arc problems through the equations of continuum magne-to-fluid-dynamics. By unifying theoretical solutions in the manner described, their usefulness in analyzing the results of experimental investigations may be greatly enhanced. The ideas center on the concept of an isothermal arc... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (1548 KB)

    The transient flow generated by a pulsed, megawatt-level, gas-fed arc with an applied magnetic nozzle has been examined with a new design piezoelectric pressure transducer. Sensor thermal conduction and accelerations have been examined and eliminated in the 500μsec period of plasma flow. Existence of a large magnitude cold gas pressure front of 20μsec duration has been reconfirmed ... View full abstract»

    For toroidal arc plasmas, the geometrical configuration, material and thickness of the discharge tube are of special importance not only for the cooling problem but also for the thermal and magnetogasdynamic behavior. In this paper, we present a new method for calculating the electromagnetic and dynamic quantities of a toroidal plasma, including the thermal properties of the confining arc wall. Re...

  • An Investigation of Coupled D. C.-Induction Arc Discharges

    Publication Year: 1973, Page(s):60 - 70

    The object of this study is to analytically determine the properties of an arc discharge generated by a combination of induction and d. c. electromagnetic fields. Induction power is supplied to the discharge by a solenoidal coil whose axis of symmetry is aligned with the applied d. c. electric field. A numerical technique is used to simultaneously solve a set of linear differential equations which... View full abstract»

    An energy balance analysis has been performed for a confined cylindrical arc column heated inductively by high-frequency fields. The analysis includes the convective energy transport due to a radial inflow in addition to the radiative and conductive transport considered in the Ellenbaas-Heller equation. The resulting non-linear, two-point boundary value equations were solved numerically. Calculati... View full abstract»

  • A Pirect Energy Recovery System Using Periodic Focusing without Grids

    Publication Year: 1973, Page(s):76 - 80
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (1534 KB)

    Results from a computational study of the efficiency of a direct energy recovery system are presented. This system is similar to R. F. Post's original (gridless) periodic-focus system. However, the computer code used here allows more flexibility than that used by Post. His code requires analytic expressions for the potentials; this code requires only the values of potential on the boundaries. Cons... View full abstract»

    A perturbation expansion for the electrostatic potential of a uniformly charged, dielectric sphere is extended to include asymmetrical electrolytes in the large radius limit. The potential, valid for qϕ/>T > 1 and small λD/a near the sphere, is solved in a similar manner to that for 1-1 electrolytes. View full abstract»

    We have studied fully-relativistic, self-consistent theoretical equilibria for the electron sheath near a magnetically insulated cathode. Such equilibria exist at stresses of 3 MV/cm for applied magnetic fields of ≥13 kG and at stresses of 5 MV/cm for applied magnetic fields of ≥20 kG in an 0.5 cm gap. The equilibrium solutions are obtained analytically as elliptic integrals, which... View full abstract»
