Buoyant turbulence kinetic energy (TKE) production in katabatic flow despite stable thermal stratification

Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Eric Richard Pardyjak

As micrometeorological research shifts to increasingly non-idealized environments, the lens through which we view classical atmospheric boundary layer theory must also shift to accommodate unfamiliar behavior. We present observations of katabatic flow over ...

Complex turbulent flow in the atmospheric boundary layer: Lab and field measurements of embedded canopy wakes

Fernando Porté Agel, Corey Dean Markfort, Fernando Carbajo Fuertes

Natural and anthropogenic fragmented landscapes are pervasive and this complexity significantly affects the structure of the atmospheric boundary layer, causing classic similarity theories to break down. This is especially true in areas affected by wake tu ...

ISTTOK Scrape-off Layer Turbulent Regimes

Paolo Ricci, Federico David Halpern, Rogério Manuel Cabete De Jesus Jorge

Use of the GBS code to successfully identify the turbulent regimes of ISTTOK's Scrape-off Layer. This was done through linear calculations and two and three dimensional nonlinear simulations. The numerical and experimental results were compared showing goo ...

Approaching the investigation of plasma turbulence through a rigorous verification and validation procedure: A practical examplea)

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella, Federico David Halpern, Fabio Riva

In the present work, a Verification and Validation procedure is presented and applied showing, through a practical example, how it can contribute to advancing our physics understanding of plasma turbulence. Bridging the gap between plasma physics and other ...

Stability analysis of boundary layers controlled by miniature vortex generators

Lorenzo Siconolfi

It is currently known that Tollmien–Schlichting (TS) waves can be attenuated by the introduction of spanwise mean velocity gradients in an otherwise two-dimensional boundary layer (BL). The stabilizing effect, associated with an extra turbulence production ...

Turbulence in Rivers

Mário Jorge Rodrigues Pereira Da Franca

The study of turbulence has always been a challenge for scientists working on geophysical flows. Turbulent flows are common in nature and have an important role in geophysical disciplines such as river morphology, landscape modeling, atmospheric dynamics a ...

Turbulence anisotropy in a compound meandering channel with different submergence conditions

Mário Jorge Rodrigues Pereira Da Franca

The understanding of the physical processes related to flows on compound meandering channels is a challenge given their highly 3D and complex characteristics. Three-dimensional ADV measurements were made in three cross-sections on a 1:20 physical Froude mo ...

Effects of plasma shaping on tokamak scrape-off layer turbulence

Paolo Ricci, Emmanuel Lanti, Sébastien Jolliet, Federico David Halpern, Fabio Riva

The understanding of the plasma dynamics in the scrape-off layer (SOL) of tokamaks is of crucial importance as we approach the ITER era. In this region, particles and heat coming from the core, through turbulent transport, flow along the magnetic field lin ...
