Dam breaks of viscoplastic material on an inclined plane.

Christophe Ancey, Steve Cochard

We report experimental results related to the dam-break problem for viscoplastic fluids. Using image processing techniques, we were able to accurately reconstruct the free-surface evolution of fixed volumes of fluid suddenly released on an inclined plane. ...

Group velocity and energy transport velocity near the band edge of a disordered coupled cavity waveguide: an analytical approach

Romuald Houdré

We develop an analytical approach to theoretically investigate light speed propagation near the band edge of a coupled cavity waveguide in the presence of residual disorder. This approach that is based on a mean field theory allows us to define the domains ...

Experimental study of the effect of a biased electrode grid attached to a limiter on plasma blob propagation in a toroidal confinement device using an ultrafast camera

Diane Virginie Marie Lançon

The main goal of this experiment is studying how blob propagation can be affected by an electrode grid in the case of an toroidal geometry with open field lines. Studies in this field are meant to better understand blob propagation in the SOLs of magnetic ...

Effect of inclined jet screen on turbidity current

Anton Schleiss, Giovanni De Cesare, Christoph Oehy

The sustainable use of reservoirs for irrigation, flood protection, water supply and hydropower may be endangered due to unavoidable reservoir sedimentation. Turbidity currents are the main process for the transport and deposit of sediments in reservoirs, ...

Mass Flux Measurement of Two Phase Dense Spray Using a Coupled Impulse Probe and PDPA Technique

Farzad Vakili Farahani

Mass flux and void fraction measurement in a multiphase dense spray is a challenging task. The Phase Doppler Particle Anemometer (PDPA) cannot provide accurate mass flux measurements in a highly turbulent multiphase spray due to the presence of non-spheric ...

Light transport regimes in slow light photonic crystal waveguides

The dispersive properties of waves are strongly affected by inevitable residual disorder in man-made propagating media, in particular in the slow wave regime. By a direct measurement of the dispersion curve in k space, we show that the nature of the guided ...
