  • 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.

  • 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.

  • 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.
