Web1 uur geleden · Nanomotors (NMs) have been suggested as the next generation of nanocarriers in drug delivery due to their autonomous motion and associated mixing hydrodynamics, especially when acting collectively as a swarm. Here, we explore the concept of enzyme-powered NMs designed as such that they can exert disruptive …

WebConference: Model for turbulent diffusion in shear flows Model for turbulent diffusion in shear flows. Full Record; Other Related Research WebShear mixing can be regarded as a combination of convection and diffusion resulting from the redistri- bution of material across slipping planes. Shear is an important feature of the mixing process by providing the driving force for convection and diffusion. great arcade hits

Fluctuations and self-diffusion of sheared granular material flows

Web31 mrt. 2004 · These fluctuations are the basis of many thermodynamic and hydrodynamic models which aim to provide a statistical description of granular systems. We present experimental results on diffusivity in dense, granular shear flows in a two-dimensional Couette geometry. We find that self-diffusivities D are proportional to the local shear rate … Web21 sep. 2024 · 1 Introduction.
