Wind-driven mixing below the oceanic mixed layer [PDF]
, 2011 This study describes the turbulent processes in the upper ocean boundary layer forced by a constant surface stress in the absence of the Coriolis force using large-eddy simulation.

On the validity of the “thin” and “thick” double-layer assumptions when calculating streaming currents in porous media [PDF]
, 2012 We find that the thin double layer assumption, in which the thickness of the electrical diffuse layer is assumed small compared to the radius of curvature of a pore or throat, is valid in a capillary tubes model so long as the capillary radius is >200 ...

Vertical distribution of particle-phase dicarboxylic acids, oxoacids and α-dicarbonyls in the urban boundary layer based on the 325 m tower in Beijing [PDF]
Atmospheric Chemistry and Physics, 2020 Vertical distributions of dicarboxylic acids, oxoacids, α-dicarbonyls and other organic tracer compounds in fine aerosols (PM2.5) were investigated at three heights (8, 120 and 260 m) based on a 325 m meteorological tower in urban Beijing ...

Compact Layer of Alkali Ions at the Surface of Colloidal Silica [PDF]
, 2007 The forces of electrical imaging strongly polarize the surface of colloidal silica. I used X-ray scattering to study the adsorbed 2-nm-thick compact layer of alkali ions at the surface of concentrated solutions of 5-nm, 7-nm, and 22-nm particles ...

Corrosion behaviour of mechanically polished AA7075-T6 aluminium alloy [PDF]
, 2010 In the present study, the effects of mechanical polishing on the microstructure and corrosion behaviour of AA7075 aluminium alloy are investigated. It was found that a nano-grained, near-surface deformed layer, up to 400 nm thickness, is developed due to

Experimental study of granular surface flows via a fast camera: a continuous description [PDF]
, 2001 Depth averaged conservation equations are written for granular surface flows. Their application to the study of steady surface flows in a rotating drum allows to find experimentally the constitutive relations needed to close these equations from ...

Increased Wear Coatings due Intrastructural Self-Correction
Журнал інженерних наук, 2019 A mechanism for blocking and subsequent annihilation of endogenous microcracks due to their intrastructural self-correction has been proposed. It has been established that during tribomechanical processes of friction interaction under conditions of ...
