Summarizing, we present a 1.5g gliding robot that can do phototaxis as a first step towards a novel palm sized self deploying microglider. To reduce the weight, we developed a 0.2g SMA actuator for rudder control that is harmoniously integrated in the airf ...
The dissipation of energy of flood discharges from water releasing structures of dams is often done by plunging jets diffusing in water and impacting on the riverbed downstream. The construction of expensive concrete structures for energy dissipation can b ...
After many years of successful operation, the JET saddle coil system will be dismantled during the 2004-2005 shutdown. A new antenna system has been designed and is being constructed to replace it and excite magneto-hydrodynamics modes in the Alfvén freque ...
Flow visualizations using endoscopes in a 21-bucket single-injector reduced scale Pelton turbine are performed for 2 operating points. 2 types of visualizations are performed with a CMOS high-speed camera: (i) an onboard visualization of the flow in the bu ...

During a recent reversed toroidal field (B-T) campaign at the Joint European Torus (JET), experiments were performed to investigate the effect on sawteeth of neutral beam injection (NBI)-driven toroidal plasma rotation counter to the direction of the toroi ...
A systematic experimental study was performed to elucidate the conditions for which cellular patterns of diluted hydrogen diffusion flames near extinction were observed. The formation of cellular instabilities was studied for several burners: jet burners ( ...
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 ...

Low pressure plasma spraying (LPPS) is a thermal spraying technique that has found a niche for low oxidation products. It uses a low pressure environment (i.e:, chamber pressure between 2 and 90 kPa) and yields supersonic plasma jets. The enthalpy probe te ...

A number of codes are in use at JET to model the edge plasma. The range of edge codes is described as is the range of physics issues being explored by these codes. The balance between focussed modelling (that looking at particular physics effects) and inte ...

The dynamic of a cavitation bubble inside a water drop is investigated in microgravity in order to analyze the interaction between the collapsing bubble and a quasispherical free surface. Tests are carried in the frame of the 42nd parabolic flight campaign ...
