Numerical investigation on the influence of mesoscopic deformation on contact area and hydraulic aperture to fracture seepage

open access: yesDeep Underground Science and Engineering, EarlyView.
Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions. In this study, the interactions between fracture closure, contact area, and hydraulic characterization of mesoscopic‐scale rough ...

Observational and Numerical Methods for Quantifying and Modeling of Turbulence in a Stratified Reservoir

open access: yesJournal of Applied Fluid Mechanics, 2016
The interplay between stratification and shear in lakes controls the vertical mixing, which is the most important mechanism affecting the transport of heat, salt, momentum and suspended and dissolved substances.

Zonal flow dynamics, modulation of mean-flow-driven fluctuations, and particle flux control in a linear magnetized plasma

open access: yesNuclear Fusion
Magnetized plasmas with radial inhomogeneities in equilibrium density and temperature naturally support a variety of electrostatic fluctuations, with drift-wave turbulence being a dominant source of outward particle transport. Controlling such turbulence

Multi-frequency vortex-induced vibrations of a long tensioned beam in linear and exponential shear flows [PDF]

open access: yes, 2013
The multi-frequency vortex-induced vibrations of a cylindrical tensioned beam of aspect ratio 200, free to move in the in-line and cross-flow directions within first a linearly and then an exponentially sheared current are investigated by means of direct

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Experiments on a barotropic rotating shear layer. Part 1. Instability and steady vortices [PDF]

open access: yes, 1999
The barotropic shear layer in a rotating fluid is studied in a laboratory experiment. Through the rotation of circular sections in the base and lid of a circular tank relative to a background rotation of the entire system, a vertical layer of strong ...

Dynamical arrest in active nematic turbulence

open access: yesPhysical Review Research
Active fluids display spontaneous turbulentlike flows known as active turbulence. Recent work revealed that these flows have universal features, independent of the material properties and of the presence of topological defects.

On bypass transition in separation bubbles: a review

open access: yesPropulsion and Power Research, 2019
Transition from laminar flow to turbulent flow is of great practical interest as it occurs in many engineering flows and often plays a critical role in aerodynamics and heat transfer performance of those flow devices.
