  • Modeling Electron Impact Ionization

    Electron impact ionization is the mainstay for plasma-based flow control actuators because it actuates in less than microseconds and the electrode configuration can be made nonintrusive to oncoming stream. In addition, when the actuator is not needed, unlike most mechanical flow control devices, it will not be parasitic and degrade performance of aerospace vehicles. The space charges induce an additional electric field potential that makes it different from the corona discharge. This chapter presents the best physics-based, multifluid model for the electron impact ionization. The physics for electron impact ionization is well known through the luminary contributions by Townsend, the ionization is evolving from the electrons collision, secondary emission, and avalanche. The secondary emission from cathode arises as controlling mechanism for all electron impact ionization. A high concentration of positive charges over an electrode creates an extremely high electrical field potential, which is comparable to the magnitude in a nuclei.

  • Ion-Flow Models: A Review

    Modeling a unipolar ion flow is a difficult task that has been shared by a number of researchers in the past century. This chapter is presented as a cursory survey of the available studies on the unipolar ion flow. Deutsch established three hypotheses, some of which are applicable under specialized conditions, regarding the unipolar ion flow in the wire-plane gap. The chapter describes some unipolar flow field problems before discussing special models namely, drift of charged spherical clouds and a method based on a simple geometrical construction describing the asymptotic ion flow for a rod-plane configuration. Estimating the Deutsch hypothesis (DH) validity is an exercise still under way and that the involved investigations persist to contradict each other.

  • Shipboard Cable Application and Verification

    Shipboard cable designations are standardized with unique symbols that directly correspond to the number of conductors constituting the cable. For shipboard electrical system design and development, cable requirements must be examined to ensure that the cable selection is within the ampacity limit of the cable as well as within the allowable voltage drop limits for specific applications. The IEEE 45 requirement is to run cable in hangers and tiers, which allows uniform heat dissipation. To prevent the grounding system from becoming an interference distribution system, the grounding must be coordinated with the shielding. A round, symmetrical cable gives the best electrical performance and resistance to deleterious effects. One reason is that round symmetry creates more uniform electrical characteristics in the cable. The insulation must have excellent dielectric properties to prevent breakdown from the stresses of voltage and current spike, corona discharges, and so forth.

  • Applications to Lightning Surge Protection Studies

    This chapter reviews representative applications of the finite-difference time domain method (FDTD) method to lightning electromagnetic pulse and surge simulations. The applications reviewed include lightning electromagnetic fields at close and far distances, lightning surges on overhead power transmission line (TL) conductors and towers, lightning surges on overhead distribution and telecommunication lines, the lightning electromagnetic environment in power substations, and lightning surges in wind-turbine- generator towers. It also includes lightning surges in photovoltaic arrays, the lightning electromagnetic environment in electric vehicles, the lightning electromagnetic environment in airborne vehicles, lightning surges and electromagnetic environment in buildings, and surges on grounding electrodes. When an overhead ground wire of a TL is struck by lightning, corona discharge will occur on this wire. Corona discharge around the ground wire reduces its characteristic impedance and increases the coupling between the ground wire and phase conductors.

  • Fundamentals of Electrical Discharges

    Natural phenomena, such as gamma rays produced by radioactive decay processes in the soil and cosmic radiation originating from solar flares and other galactic objects, can ionize the air molecules. This chapter first discusses ionization and deionization processes in gases. This is followed by a discussion on ionization and attachment coefficients. Two typical breakdown mechanisms occur in gases, each of them operating under specifically favorable conditions: Townsend's mechanism and the streamer mechanism. Corona discharges in air can burn on the overstressed zones of hot electrodes. This kind of discharge occupies a short layer, attached to the energized conductor. When a conductor is in corona, then the electric field on the surface is somehow influenced by the surrounding ion space charge. Kaptzov's hypothesis (KH) relates to the assumption that the space charge emitted into the interelectrode gap is in amounts that hold the surface field at the onset level.

  • Experimental Investigation on Unipolar Ion Flows

    The amount of available experimental data concerning corona originated space- charge flows is large; however, there is a persistent need for exploring the still overlooked or underestimated supplementary performances. These can emerge from special ion-flow field structures and can be monitored while changing pivotal geometrical parameters one at a time. Owing to the informative character of some individual sources, a demanding experimental strategy has been adopted for making the investigation on unipolar ion flows as complete as possible. A number of sources have been categorized, in this chapter, in function of the injection system and methodically monitored. Therefore, a suspended electrode becomes a V-shaped wire, a two-conductor bundle, an inclined rod, a partially sheathed wire, a pointed-pole sphere and a straight wedge. A 3D generalization of the experimentally discovered performances is given in light of the deep connection between the acknowledged general character of the homeomorphism and the notion of invariance.
