Pre-sheath density drop induced by ion-neutral friction along plasma blobs and implications for blob velocities

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Joaquim Loizu Cisquella

The pre-sheath density drop along the magnetic field in field-aligned, radially propagating plasma blobs is investigated in the TORPEX toroidal experiment [Fasoli et al., Plasma Phys. Controlled Fusion 52, 124020 (2010)]. Using Langmuir probes precisely al ...

Study of the Ne(3P2) + CH3F Electron-Transfer Reaction below 1 K

Andreas Osterwalder, Justinas Jankunas, Benjamin Bertsche

Relatively little is known about the dynamics of electron-transfer reactions at low collision energy. We present a study of Penning ionization of ground-state methyl fluoride molecules by electronically excited neon atoms in the 13 μeV–4.8 meV (150 mK–56 K ...

Plasma Diagnostics and Modelling of Nanosecond Pulsed Surface Dielectric Barrier Discharge Actuators

Sami Goekce

During the past years, an increasing number of studies have been conducted on the use of electrical discharges for the stabilization of airflows (plasma flow control). Electrical gas discharges transfer energy and momentum to the gas through collisions of ...

Debris-Blocking Sensitivity of Piano Key Weirs under Reservoir-Type Approach Flow

Anton Schleiss, Michael Pfister

The collection of floating woody debris at flow control structures, such as spillways and weirs, can potentially result in reduced discharge efficiency (higher upstream head for a given weir discharge). Compared to less hydraulically-efficient control stru ...

DC Breakdown in gases for complex geometries from high vacuum to atmospheric pressure

Ralph Schnyder

This thesis presents an experimental investigation and a numerical simulation of breakdown in a ring assembly. Previous works are mostly limited to breakdown in simple geometries such as parallel plates or pin-to-plate. Here we discuss the effect of more c ...

Simulation of Electrical Discharge Initiated by a Nanometer-Sized Probe in Atmospheric Conditions

Jürgen Brugger

In this paper, a two-dimensional nanometer scale tip-plate discharge model has been employed to study nanoscale electrical discharge in atmospheric conditions. The field strength distributions in a nanometer scale tip-to-plate electrode arrangement were ca ...

Direct current breakdown in gases for complex geometries from high vacuum to atmospheric pressure

Christoph Hollenstein, Alan Howling, Ralph Schnyder

The demand for improved performances of power transmission devices requires ever smaller dimensions and higher working voltages which lead to increased risk of breakdown, for example, in satellite slip rings. Previous works are mostly limited to breakdown ...

Effect of driftwood on hydraulic head of Piano Key weirs

Anton Schleiss, Michael Pfister

Driftwood is often transported by a river course during flood events and can be problematic where it accumulates at hydraulic structures. Near obstacles, driftwood can block and thus reduces the open flow area for water passage, resulting in a lowered disc ...
