Advances in research on turbulence structure in vegetated open channel flows

Shui kexue jinzhan, 2014
Aquatic plants in natural rivers have important effects on turbulence structure. In the presence of vegetation,river flows become more intensely mixed and their turbulent structures are more complicated.

Narrative-based writing for coherent technical documents [PDF]

, 2007
Narrative-based writing is a technique that was developed to address the lack of support for document coherence. The technique depends on the production of a story-like executive summary of the document called a DN (Document Narrative).

Time-Resolved Particle Image Velocimetry Measurements and Proper Orthogonal Decomposition Analysis of Unsteady Flow in a Centrifugal Impeller Passage

Frontiers in Energy Research, 2022
Time-resolved particle image velocimetry (TR-PIV) measurements were conducted to analyze the unsteady flow field developing in a centrifugal pump. The flow structures in the impeller passage under different flow rates were investigated.

Structural analysis of dynamic-controlled jet using DNS

Journal of Fluid Science and Technology, 2014
In order to develop a new mixing procedure, we conduct DNS (direct numerical simulation) of dynamic controlled free jets. As the dynamic control, it is assumed that the inflow of jet rotates around the streamwise axis.

Identification of Thermally-Tagged Coherent Structures in the Zero Pressure Gradient Turbulent Boundary Layer [PDF]

, 2013
A zero pressure gradient boundary layer over a flat plate is subjected to step changes in thermal condition at the wall, causing the formation of internal, heated layers.

Ligand-Structure-Dependent Coherent Vibrational Wavepacket Dynamics in Pyrazolate-Bridged Pt(II) Dimers

, 2022
Bimetallic transition metal complexes have gained increasing attention because of their versatile functions in solar energy conversion and photonics applications arising from intermetal electronic coupling.

Numerical Investigation on Flow Structures and Mixing Performances of Vector-Controlled Free Jet using DNS

Journal of Fluid Science and Technology, 2011
In order to develop a new mixing procedure, we conduct DNS (direct numerical simulation) of vector controlled free jets. The inflow velocity of jet is periodically oscillated perpendicular to the jet axis.

Transition to Equilibrium and Coherent Structure in Ideal MHD Turbulence

Fluids, 2023
Transition of ideal, homogeneous, incompressible, magnetohydrodynamic (MHD) turbulence to near-equilibrium from non-equilibrium initial conditions is examined through new long-time numerical simulations on a 1283 periodic grid.

Lagrangian measurements of turbulent dissipation over a shallow tidal flat from pulse coherent Acoustic Doppler Profilers

, 2012
We present high resolution (25 mm spatial, 8 Hz temporal) profiles of velocity measured over a shallow tidal flat using pulse-coherent Acoustic Doppler Profilers mounted on surface drifters.

On representing claims for coherent risk measures [PDF]

, 2007
We consider the problem of representing claims for coherent risk measures. For this purpose we introduce the concept of (weak and strong) time-consistency with respect to a portfolio of assets, generalizing the one defined in Delbaen [7]. In a similar
