Simulation Study of High Frequency Pulsed DC Discharges in Nitrogen

L. Tong [1],
[1] Keisoku Engineering System Co., Ltd., Tokyo, Japan

Pulsed DC technology has led to the design of cost-effective deposition systems and to improved film properties, compared to conventional rf systems. In this work, a two-dimensional finite element model is used to investigate the high frequency pulsed DC discharges in nitrogen. The study ... Read More

Three-Dimensional Numerical Simulation of Arc Motion Between Bus-Bar Electrodes

[1] Université d’Orléans, Orléans, France
[2] Zodiac Aero Electric, Zodiac Aerospace, Montreuil, France

The knowledge of the behavior of electric arcs between plane electrodes is in high interest due to their presence in industrial applications such as low voltage circuit breakers. In this contribution, numerical simulations of an electric arc displacement due to electro-magnetic forces ... Read More

Numerical Model of Mars Electrostatic Precipitator

J. Wang[1], J. Malissa[1], J. Phillips III[1], M. Johansen[1], C. Calle[1]
[1]NASA Kennedy Space Center, USA

NASA’s future human exploration missions will require chemical processing plants to convert local resources into consumables to support astronaut activities [1]. The thin and mostly carbon dioxide atmosphere of Mars is estimated to have 5 – 10 particles/cm3 with diameter of 3.2 – 5 μm ... Read More

Study of Thermo-Electrical and Mechanical Coupling During Densification of a Polycrystalline Material Using COMSOL

F. Mechighel[1,2,3], B. Pateyron[1], M. El Ganaoui[1], and M. Kadja[3]
[1]CNRS SPCTS UMR 6638, Universite de Limoges, France
[2]Département de Génie Mécanique, Universite de Annaba, Algerie
[3]Département de Génie Mécanique, Universite de Constantine, Algerie

Spark Plasma Sintering (SPS) is a promising rapid consolidation technique that allows a better understanding and manipulation of sintering kinetics and therefore makes it possible to obtain polycrystalline materials (ceramic or metallic) with tailored microstructures. A numerical ... Read More

Keep it Simple and Learn More - On a Stationary Study of a Time-Dependent Problem

B. Baumann [1], J. Schwieger [1, 2], U. Stein [1], M. Wolff [1],
[1] Hamburg University of Applied Sciences, Hamburg, Germany
[2] University of the West of Scotland, Paisley Campus, United Kingdom

Today’s driver hardware for High-intensity discharge (HID) lamps is bulky, expensive and not particularly energy-efficient. A downscaling of the devices seems possible by increasing the operation frequency from typically 400 Hz to some hundred kilohertz. However, efforts to design high ... Read More

Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture

I. Bitharas [1], A. Moore [1],
[1] Heriot-Watt Univerisity, Edinburgh, UK

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... Read More

HIIPER Space Propulsion Simulation Using AC/DC Module

Z. Chen [1], D. Ahern [1], G. Miley [1],
[1] University of Illinois at Urbana-Champaign, Urbana, IL, USA

The Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER) is an electric space propulsion concept being studied that utilizes a helicon source to generate a plasma and metal grids from inertial electrostatic confinement (IEC) fusion experiments to accelerate ions, generating a ...
