Dynamics of wind-induced coastal upwelling and interbasin exchange in Lake Geneva during winter: Implications for deepwater renewal

Water quality in lakes is closely linked to hydrodynamics and often dominated by stratification, limiting the exchange between the epi- and hypolimnion. Thus, the vertical redistribution of biogeochemical tracers such as dissolved oxygen and nutrients by c ...

Roll-up region of tip vortex: numerical investigation

Mohamed Farhat, Azin Amini, Matthieu Dreyer, Ali Amini, Martino Reclari

The appearance of gas-filled vortices at the tip of hydraulic machines blades is usually associated with increase of losses, vibrations, noise and erosion risk. The understanding of the roll-up region, where the boundary layer on the pressure side crosses ...

Flow Adjustment Inside and Around Large Finite-Size Wind Farms

Fernando Porté Agel, Ka Ling Wu

In this study, large-eddy simulations are performed to investigate the flow inside and around large finite-size wind farms in conventionally-neutral atmospheric boundary layers. Special emphasis is placed on characterizing the different farm-induced flow r ...

Mitigation of Wind-Induced Vibrations in Long-Span Bridges using a Distributed Flap System

Klara Maria Boberg

Since the collapse of the Tacoma Narrows Bridge more than 70 years ago suppressing wind-induced instabilities has been a key aspect of the design of long-span bridges. The intensive experimental and theoretical research in wind engineering allowed research ...

Inter-Plane Communication Methods for 3-D ICs

Giovanni De Micheli, Vasileios Pavlidis, Somayyeh Rahimian Omam

Three-dimensional (3-D) integration is an emerging candidate for implementing high performance multifunctional systems-on-chip. Employing an efficient medium for data communication among different planes is a key factor in achieving a high performance 3-D ...

A new boundary condition for large-eddy simulation of boundary-layer flow over surface roughness transitions

Fernando Porté Agel, Mahdi Abkar

Large-eddy simulations are performed to evaluate the performance of the surface boundary condition downwind of a rough-to-smooth surface transition. Two types of boundary conditions are tested: (1) The standard formulation based on local application of the ...

A scalable and oblivious atomicity assertion

Rachid Guerraoui, Marko Vukolic

This paper presents SOAR: the first oblivious atomicity assertion with polynomial complexity. SOAR enables to check atomicity of a single-writer multi-reader register implementation. The basic idea underlying the low overhead induced by SOAR lies in greedi ...

Pre- and Post-Transition Behavior of Shear Thickening Fluids in oscillating Shear

Véronique Michaud, Pierre-Etienne Bourban, John Christopher Plummer, Christian Fischer

The dynamic shear-thickening behavior of concentrated colloidal suspensions of fumed silica in polypropylene glycol has been investigated. Dynamic frequency sweeps showed that, for any given solids concentration, the complex viscosity at different imposed ...
