Improvements to the dynamic wake meandering model by incorporating the turbulent Schmidt number

Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort

Predictions of the dynamic wake meandering model (DWMM) were compared to flow measurements of a scanning Doppler lidar mounted on the nacelle of a utility-scale wind turbine. We observed that the wake meandering strength of the DWMM agrees better with the ...

Properties of plasma turbulence in the periphery of diverted tokamaks

Paolo Ricci, Paola Paruta, Maurizio Giacomin, Carrie Fiona Beadle

The turbulent plasma dynamics in the periphery of a tokamak plays a key role in determining its overall performances. In particular, it governs the confinement properties of the device, through the formation of a transport barrier associated with the L-H t ...

Disentangling turbulence in the plasma boundary of diverted tokamaks

Carrie Fiona Beadle

A non-field aligned coordinate system was recently implemented in GBS, a three-dimensional drift-reduced Braginskii fluid code to simulate turbulence in the plasma periphery of tokamaks. This avoids the singularity present in field-aligned coordinates at t ...

Absolute/convective secondary instabilities and the role of confinement in free shear layers

François Gallaire, Cristobal Manuel Arratia Martinez, Saviz Mowlavi

We study the linear spatiotemporal stability of an infinite row of equal point vortices under symmetric confinement between parallel walls. These rows of vortices serve to model the secondary instability leading to the merging of consecutive (Kelvin-Helmho ...

A Chip-Level Post-CMOS Via-Last Cu TSV Process for Multi-Layer Homogeneous 3D Integration

Seniz Esra Küçük, Yusuf Leblebici, Woo Yeong Cho

In this paper, a die-level CMOS post-processing scheme for 3D integration using the via-last approach is presented for multi-layer stacking. The process includes TSV fabrication, chip-to-chip bonding, and finally the TSV filling with Cu electroplating. The ...

Aerosol water parameterisation: A single parameter framework

Athanasios Nenes

We introduce a framework to efficiently parameterise the aerosol water uptake for mixtures of semi-volatile and non-volatile compounds, based on the coefficient, vi. This solute-specific coefficient was introduced in Metzger et al. (2012) to accurately par ...

Kelvin waves in Lake Geneva

Ulrich Lemmin, Damien Bouffard

The passage of Kelvin waves in Lake Geneva after strong wind events was experimentally investigated in 1987 and 2002 using thermistor chains, current meters and Acoustic Doppler Current Profilers (ADCP) probing the whole water column, including the bottom ...

Transient perturbation growth in time-dependent mixing layers

Cristobal Manuel Arratia Martinez

We investigate numerically the transient linear growth of three-dimensional (3D) perturbations in a homogeneous time-evolving mixing layer in order to identify which perturbations are optimal in terms of their kinetic energy gain over a finite, predetermin ...

Thermal dynamics at surfaces

Harald Brune

The present paper describes what happens at the surface of a crystal as its temperature steadily increases from zero Kelvin close to the bulk melting temperature. We treat thermal motion, such as the diffusion of individual adatoms establishing mass transp ...

Comportement au jeune âge et différé d'un BFUP écrouissant sous les effets thermomécaniques

Aicha Kamen

This thesis is dedicated to study the early age behavior and time dependant as well as the thermo-mechanical response under restraint of a hardening Ultra High Performance Fiber Reinforced Concrete (UHPFRC). The knowledge of the UHPFRC behavior is indispen ...
