We have investigated the mechanisms involved in dissolved oxygen (DO) transfer from a turbulent flow to an underlying organic sediment bed, populated with DO-absorbing bacteria, relying on the coupling between the bio-geochemistry of the sediment layer and large-eddy simulation for the transport on...
mass transferLarge-Eddy Simulationgas-liquid interfacecoherent structureThis paper reports some new results concerning the structure of the concentration field and the mechanisms of mass transfer at flat, turbulent, gas–liquid interfaces, especially in the limit of high-Schmidt numbers. The problem is...
ROBILLARD, in Transport Phenomena in Heat and Mass Transfer, 1992 4 RESULTS All calculations were performed for a Prandtl number Pr = 1 and a cavity aspect ratio R = 2 at different Rayleigh numbers ranging from Ra = 2 × 103to Ra = 105. Results are presented below as functions of the ...

Numerical studies of vortex-induced extinction/reignition relevant to the near-field of high-Reynolds number jets This work is motivated by the need to understand physical mechanisms governing near-field phenomena, such as flame lift-off, in high-Reynolds number jet fl... R Venugopal,J Abraham...
We consider the generation of magnetic fields under astrophysical conditions. Principal attention is paid to "dynamo" mechanisms, i.e., mechanisms in which the energy of the magnetic field is drawn from the kinetic energy of plasma motio... SI Vainshtein,YB Zel'Dovich - 《Uspekhi Fizicheski...
Many cell types secrete EVs, which are nano-sized vesicles composed of a double-layered lipid membrane structure. EVs, brimming with bioactive molecules, orchestrate cellular dialogue, thereby playing significant parts in the biological mechanisms of inflammation, oxidative stress, cellular senescence, ...
The analogy between heat and mass transfer does not strictly hold, with the experimental results being close to the Lewis Law 2 [10] 2005 Experiment 0.6–1.0 • The Le is insensitive to changes in fin spacing at low Reynolds numbers • A slight drop of Le was seen with the decrease ...
exposes the three fundamental transport mechanisms that underly redistribution of ϕ: transport by particle motion or “advection” (Ja); transport by Brownian motion or “diffusion” (Jd); injection/removal by internal sources/sinks (R ). The diffusive flux Jd is referred to as Fick's law ...
This is essentially a self-preserving relation independent of time, material properties and sintering mechanisms that is used to estimate the equivalent primary particle diameter and number in aggregates. The aggregate morphology is quantified by the effective fractal dimension (Df) and mass-mobility ...
