Heat transfer enhancement to a confined impinging synthetic air jet [PDF]

, 2013
Heat transfer to confined, un-ducted and ducted impinging synthetic air jets is investigated experimentally. The influence of ducting on the cooling performance of synthetic air jets is of particular interest.

Spectra of magnetic perturbations triggered by pellets in JET plasmas [PDF]

, 2010
Aiming at investigating edge localised mode (ELM) pacing for future application on ITER, experiments have been conducted on JET injecting pellets in different plasma configurations, including high confinement regimes with type-I and type-III ELMs, low ...

Synthetic NPA diagnostic for energetic particles in JET plasmas [PDF]

, 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.

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.

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.

Radiation from accelerated particles in relativistic jets with shocks, shear-flow, and reconnection

EPJ Web of Conferences, 2013
We have investigated particle acceleration and shock structure associated with an unmagnetized relativistic jet propagating into an unmagnetized plasma for electron-positron and electron-ion plasmas.
