On the Wake Properties of Segmented Trailing Edge Extensions
Changes in the amount and the distribution of mean and turbulent quantities in the free shear layer wake of a 2D National Advisory Committee for Aeronautics (NACA) 0012 airfoil and an AR 4 NACA 0012 wing with passive segmented rigid trailing edge (TE ...

Identifying Characteristics of Wildfire Towers and Troughs
Wildfire behavior is dictated by the complex interaction of numerous physical phenomena including dynamic ambient and fire-induced winds, heat transfer, aerodynamic drag on the wind by the fuel and combustion.

Lagrangian flow measurements and observations of the 2015 Chilean tsunami in Ventura, CA
Tsunami‐induced coastal currents are spectacular examples of nonlinear and chaotic phenomena. Due to their long periods, tsunamis transport substantial energy into coastal waters, and as this energy interacts with the ubiquitous irregularity of ...

Coherent Momentum Exchange above and within a Scots Pine Forest
Biorthogonal decomposition (BOD) is used to detect and study synchronous coherent structures occurring at multiple levels in the vertical momentum flux (u′w′) within and above a planted Scots pine forest during a 12-week continuous measurement period. In

The representation of turbulent fluxes during oceanic convective events is important to capture the evolution of the oceanic mixed layer. To improve the accuracy of turbulent fluxes, we examine the possibility of adding a non‐local component in their ...

Randomness Representation of Turbulence in Canopy Flows Using Kolmogorov Complexity Measures
Turbulence is often expressed in terms of either irregular or random fluid flows, without quantification. In this paper, a methodology to evaluate the randomness of the turbulence using measures based on the Kolmogorov complexity (KC) is proposed.

Sequential and Parallel Algorithms to Compute Turbulent Coherent Structures
The behavior of turbulent flows remains a significant unsolved problem in physics. Recently, a large quantity of effort has been directed toward understanding the non-linear interactions of the different flow structures in order to address this challenge.

The Lagrangian approach (LA) in ocean modelling relies on a dense set of trajectories of virtual particles that can be computed using velocity fields and on a subsequent analysis of entangled trajectories of particles.

Experience in developing jet noise silencers
In this paper, we investigate the acoustic characteristics of subsonic jet streams exposed to high-frequency noise. The main device generating high-frequency sound was a system consisting of peripheral nozzles located around the main (base) nozzle.
