Experimental study on Scour due to simultaneous wall and impinging circular jet

In this study the scour mechanism and the effect of some of the important parameters such as jet velocities, impinging jet distance from the upstream wall and tailwater depth on the longitudinal scour profile due to 3d simoultaneous wall and impinging jet ...

Response of an Embedded Block Impacted by High-Velocity Jets

Matteo Paolo Elia Antonio Federspiel

High-velocity plunging jets, issuing from ood release structures of dams, may result in scouring of the rocky riverbed and even endanger the foundation of the dams. Assessment of the scour extent is essential to ensure the safety of the dam and appurtenant ...

Effects of Swirl Velocities From Fan Assemblies Mounted on Lifting Surfaces

Alexandros Terzis, Charilaos Kazakos, Nikolaos Papadopoulos

The penetration of a jet of fluid into a traversal moving stream is a basic configuration of a wide range of engineering applications, such as film cooling and V/STOL aircrafts. This investigation examines experimentally the effect of blowing ratio of fans ...

Cavitation bubble behavior inside a liquid jet

François Avellan, Mohamed Farhat, Peter Monkewitz, Etienne Robert, Jacques Lettry

The growth and collapse of laser-induced vapor cavities inside axisymmetric free-falling liquid water jets have been studied. Bubbles of different size are generated at various distances from the jet axis and the effects on the jet interface are recorded b ...

Discrepancy between modelled and measured radial electric fields in the scrape-off layer of divertor tokamaks: a challenge for 2D fluid codes?

Richard Pitts, Jan Horacek, Marco Wischmeier

Examination of radial electric field (E,.) profiles in the scrape-off layer (SOL) of ASDEX Upgrade (AUG) and JET revealed large discrepancies between 2D fluid edge modelling and experiment. Experimental profiles of plasma potential (V-p) in the outer (low ...

On the Dynamic of Cavitation Bubbles and Their Interaction with Solid and Free Surfaces

Mohamed Farhat

The cavitation phenomenon, which is due to a pressure drop in liquid flows, may be responsible of noise and vibration as well as efficiency alteration and material erosion. A tremendous work has been already performed to better understand the onset and dev ...

Measurement of the instability threshold for toroidal Alfven eigenmodes in JET plasmas with forward and reversed magnetic field

Ambrogio Fasoli, Duccio Testa

In this paper we have investigated the effect of reversing the direction of the magnetic field and plasma current, hence the ion del B-drift direction, on the instability threshold of toroidal Alfven eigenmodes with toroidal mode number (n) in the range ve ...

Modelling of Alfven waves in JET plasmas with the CASTOR-K code

Ambrogio Fasoli, Duccio Testa

A hybrid magnetohydrodynamic (M H D)-gyro-kinetic model CASTOR-K developed for the study of Alfven eigenmode (AE) stability in the presence of energetic ions has been applied to the interpretation of recent measurements of Alfven waves in JET. These includ ...

Studies of D-D Fusion Reactivity in High-Temperature Jet Plasmas

Henri Weisen

The D-D fusion reactivity from JET plasmas has been optimized by using combined neutral beam injection and radiofrequency heating. Reaction rates of up to 2.9 x 10(16) reactions per second (equivalent to neutron emission rates of 1.45 x 10(16) neutrons per ...
