254. Effects of temperature dependence of electrical and thermal conductivities on the heating of a one dimensional conductor

Foivos Antoulinakis (University of Michigan, Ann Arbor, MI 48109, USA)

Plasmas, Discharges, and Electromagnetic Phenomena

Oral Presentation

Joule heating limits the operation of most current carrying components and devices, especially in nanoscale circuits such as carbon nanofiber based field emitters, graphene electronics, and nanolasers [1]. For many materials of interest it is important to consider the temperature dependence of the thermal and electrical conductivities when calculating the effects of Joule heating. We examine...

59. Transient Electromagnetic Field Reconstruction from Sets of Non-Periodic Oscillations

William Feilner (Texas Tech University)

08/07/2016, 15:45

Accelerators, Beams, and Repetitive Pulsed Power

Oral Presentation

Arbitrary transient electric field shapes are generated in free space utilizing a set of transient signals with proper shape, amplitude, and time shift. Akin to wavelets in signal processing, brief, non-periodic oscillations are superimposed at a pre-selected location in space to effect destructive and constructive interference. With a properly chosen signal set, an entirely different...

142. Electric field analysis of different compact electrodes for high voltage pulsed electric field applications in liquid food

Mrs RAMYA RAMASWAMY (BSAU)

Plasmas, Discharges, and Electromagnetic Phenomena

Oral Presentation

A 2D and 3D electromagnetic simulation has been performed on compact electrode designs aimed to obtain higher electric field distribution between the high voltage and ground electrode, which ensures high bacterial inactivation in liquid food. The electric field simulations are performed for applied voltages of 1kV to 5kV. For the round edged design, the transmembrane potential of 1V is...

172. Pulsed plasmas for two environmental applications: Power-to-Methane and pollution control

Bert van Heesch (TUe)

08/07/2016, 16:15

Biological, Medical, and Environmental Applications of Power Modulators

Poster Presentation

Nanosecond pulsed plasmas at ambient conditions can be tailored to energize chemical processes that help to cure environmental problems. We report here two application areas: industrial emission control and fuel synthesis. A short review will be presented of the development and industrial performance of a pilot size installation for on-site emission abatement [1]. The pilot installation has...

208. Improvement on the Ionization Rate of Hall Thruster with High Voltage

Yongjie Ding

Plasmas, Discharges, and Electromagnetic Phenomena

Oral Presentation

With the development of spaceflight mission, high special impulse becomes significant trend of Hall Thruster. Improving the discharge voltage is the most effective way to achieve high special impulse. Because of the limit of total power, the increase of voltage means the decrease of mass flow rate of neutral propellant, and ionization rate is significantly related to the neutral density....

34. Discharge properties of microsecond pulse driven Argon plasma jet arrays

Tao Shao (Institute of Electrical Engineering, Chinese Academy of Science)

Plasmas, Discharges, and Electromagnetic Phenomena

Poster Presentation

Atmospheric pressure plasma jets (APPJs) have attracted much attention due to their flexibility, low cost and ability to treat remote objects. By grouping individual jets together to form jet arrays is a good solution for large area treatment. Most of the reports generated plasma jet arrays using He as discharge gas. However, Ar is more economic than He. But, due to its high breakdown voltage...

278. Evolution of Partial Discharge of Oil-paper insulation under Long-term AC Voltage

08/07/2016, 17:15

Dielectrics, Insulation, and Breakdown

Poster Presentation

Internal insulation defects of oil-immersed transformers are common because of flaws in both manufacturing and transportation process. Partial discharge (PD) activity caused by insulation defects may occur at rated voltage condition, leading to deterioration of material, which results in breakdown of insulation. Feature parameters of PD are closely related to the performance of insulation...
