Reduction of bend scour with an air-bubble screen - morphology and flow patterns

Anton Schleiss, Koen Blanckaert, Violaine Dugué

The interplay between streamwise flow, curvature-induced secondary flow, sediment transport and bed morphology leads to the formation of a typical bar-pool bed morphology in open-channel bends. The associated scour at the outer bank and deposition at the i ...

Quantitative imaging of flux vortices in the type-II superconductor MgB2 using cryo-Lorentz transmission electron microscopy

Cécile Hébert, Marco Cantoni, Fabrizio Carbone, Duncan Thomas Lindsay Alexander, Janusz Andrzej Karpinski, Mathieu Julien Gino Cottet

Imaging of flux vortices in high quality MgB2 single crystals has been successfully performed in a commercial field-emission gun-based transmission electron microscope. In cryo-Lorentz microscopy, the sample quality and the vortex lattice can be monitored ...

Resilience of river flow regimes

Andrea Rinaldo, Gianluca Botter

Landscape and climate alterations foreshadow global-scale shifts of river flow regimes. However, a theory that identifies the range of foreseen impacts on streamflows resulting from inhomogeneous forcings and sensitivity gradients across diverse regimes is ...

An aggregated dynamic flow model for pedestrian movement in railway stations

Michel Bierlaire, Bilal Farooq, Flurin Silvan Hänseler

Pedestrian flows occurring in train stations are multi-directional and highly non-stationary. In this work, we develop a cell-based pedestrian flow model capable of describing flow patterns arising when a multitude of trains arrive and depart in close succ ...

Spatial-Mode Discrimination in Guided and Antiguided Arrays of Long-Wavelength VCSELs

Elyahou Kapon, Nicolas Volet, Vladimir Iakovlev

Three means of optical confinement imposed on InAlGaAs/InP 1.3 mu m VCSEL arrays are investigated with self-consistent numerical model of laser operation. Laterally patterned tunnel junction (TJ), in-build guiding realized with air-gap patterning, and anti ...

Dewetting-driven hierarchical self-assembly of small semiconducting molecules

Roland Hany, Jakob Heier, Gian-Luca Bona, Raffaele Mezzenga

We describe the self-organization of PCBM and a cyanine dye on chemically patterned surfaces during spin coating from solution. On homogeneous surfaces, a transient bilayer forms, which in a later stage decomposes into PCBM droplets in a matrix of the cyan ...

Flow patterns induced by a bubble screen in a sharply curved flume based on Acoustic Doppler Velocity Profiler measurements

Anton Schleiss, Koen Blanckaert, Violaine Dugué

Open-channel bends are characterized by a bed morphology where erosion occurs near the outer bank and a point bar develops at the inner bend. This morphology is induced by complex interactions between the streamwise flow, the curvature-induced secondary fl ...

Analytical method to predict two-phase flow pattern in horizontal micro-capillaries

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid

An a priori prediction of multiphase flow pattern in micro-capillaries or microstructured reactors (MSR) is required for their rational design. The state-of-the-art numerical models require huge computational efforts. In the present work, an analytical mod ...
