Spatial Variability of Turbulent Mixing From an Underwater Glider in a Large, Deep, Stratified Lake

Alfred Johny Wüest, Damien Bouffard, Sébastien Lavanchy, Oscar Rodrigo Sepúlveda Steiner, Bieito Fernandez Castro, Alexander Lebaron Forrest

Recent efforts using microstructure turbulence measurements have contributed to our understanding of the overall energy budget in lakes and linkages to vertical fluxes. A paucity of lake-wide turbulence measurements hinders our ability to assess how repres ...

LeXPLORE: A floating laboratory on Lake Geneva offering unique lake research opportunities

Alfred Johny Wüest, Natacha Tofield-Pasche, Damien Bouffard, Sébastien Lavanchy

Environmental sciences depend heavily on observational data. Successful studies of ecological processes in lakes require in-situ data that cover the relevant temporal scales from milliseconds to entire seasons. Temporal and spatial coverage requirements re ...

Design and durability of titanium adhesive joints for marine applications

Véronique Michaud, Basile Golaz, Sébastien Lavanchy

Comparative measurements of strength and Griffith's critical strain energy release rate G(Ic) were carried out on adhesively bonded joints with different surface treatments of titanium, before and along 13 weeks of accelerated aging in salted or deionized ...

Experimental determination of the permeability of textiles: A benchmark exercise

Véronique Michaud, Sébastien Lavanchy, Wei Wu

In this international permeability benchmark exercise, in-plane permeability data for two reinforcement fabrics, obtained using a total of 16 different experimental procedures, were compared. Although, for each procedure, the results appear consistent, dif ...

Experimental investigation of the effect of the mould thermal expansion on the development of internal stresses during carbon fibre composite processing

René Salathé, Véronique Michaud, Sébastien Lavanchy, Rodrigue Chatton

The influence of the mould material on the build-up of internal stresses during autoclave cure of carbon fibre composites was investigated using embedded optical fibre Bragg gratings. Unidirectional and cross-ply laminates were cured on four flat moulds: a ...

Influence of the mould thermal expansion on composite stress build-up during curing

Véronique Michaud, Sébastien Lavanchy

The influence of the mould material on the build-up of internal stresses during autoclave cure of a unidirectional carbon fibre composite material was investigated using embedded optical fibre Bragg gratings. Four flat moulds (i.e. aluminium, steel, carbon ...
