Effect of the duty cycle on the spark-plug plasma synthetic jet actuator
EPJ Web of Conferences, 2016 A promising novel actuator called Spark-Plug Plasma Synthetic Jet (SPSJ) has been developed in Atmospheric Plasma Research Laboratory at Niğde University. It generates electrothermally high synthetic jet velocity by using high voltage.

Synthetic NPA diagnostic for energetic particles in JET plasmas [PDF]
Journal of Instrumentation, 2017 Neutral particle analysis (NPA) is one of the few methods for diagnosing fast ions inside a plasma by measuring neutral atom fluxes emitted due to charge exchange reactions. The JET tokamak features an NPA diagnostic which measures neutral atom fluxes and energy spectra simultaneously for hydrogen, deuterium and tritium species.

A Calibrated Lumped Element Model for the Prediction of PSJ Actuator Efficiency Performance
Actuators, 2018 Among the various active flow control techniques, Plasma Synthetic Jet (PSJ) actuators, or Sparkjets, represent a very promising technology, especially because of their high velocities and short response times.

Through the Looking Glass: Faraday Conversion in Turbulent Blazar Jets
Galaxies, 2016 Faint levels of circular polarization (Stokes V) have been detected in several relativistic jets. While typically less than a few percent, circular polarization can give us critical insight into the underlying nature of the jet plasma.

Separation control with plasma synthetic jet actuators
International Journal of Aerodynamics, 2013 In the framework of the PLASMAERO project funded by the European Community, ONERA and CNRS laboratories develop plasma synthetic jet actuators, in order to demonstrate the potential of such electrical devices to act on aerodynamic phenomena like separated flows.

Pre-switching bifurcation of a slender jet [PDF]
, 2016 In this work, we study the near-field of the jet flow exiting a slot-model with aspect ratio 7.5:1. The core of the slender jet separates into two streams which subsequently merge recomposing a single core jet.

Humidity Characteristics of Plasma Synthetic Jet Actuator
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2008 This paper describes humidity characteristics of Plasma Synthetic Jet Actuator (PSJA). PSJA is flow control device using the Electro Hydro Dynamic (EHD) effect of the glow-discharge. PSJA can be downsized, controlled easily, and has quick control response.

Experimental investigation on frequency characteristics of plasma synthetic jets
Physics of Fluids, 2017 The performance of a two-electrode plasma synthetic jet actuator (PSJA) is investigated for a wide range of dimensionless actuation frequencies ( f*) using high-speed phase-locked particle imaging velocimetry measurements. The jet-induced velocity fields in the axisymmetric plane are measured during both transient and steady working stages of the PSJA.

3D Simulations of Relativistic Precessing Jets Probing the Structure of Superluminal Sources [PDF]
, 2003 We present the results of a three-dimensional, relativistic, hydrodynamic simulation of a precessing jet into which a compact blob of matter is injected.
