Study of slime water mixing process intensification using impingement flow regulation
Meitan kexue jishu, 2023 slime water generally contains a large number of highly dispersed suspended particles, making solid-liquid separation difficult. Strengthening fluid mixing and particle collision by regulating turbulence is an effective way to achieve solid-liquid ...

Jet sharpening by turbulent mixing [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011 Jets or localized strong currents in planetary atmospheres, as well as in the Earth’s oceans, are often associated with sharp potential-vorticity gradients owing to the inherent balance exhibited by these flows. Here, we explore and quantify jet sharpening in a simple idealized single-layer quasi-geostrophic model on a mid-latitude

Numerical analysis of reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion [PDF]
, 2009 The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations (DNS) of three-dimensional, turbulent Bunsen flames with reduced methane-air ...

Remote Sensing, 2020 Turbulent mixing is critical in affecting urban climate and air pollution. Nevertheless, our understanding of it, especially in a cloud-topped boundary layer (CTBL), remains limited. High-temporal resolution observations provide sufficient information of

Turbulent mixing at a stable density interface : the variation of the buoyancy flux–gradient relation [PDF]
, 2007 Experiments conducted on mixing across a stable density interface in a turbulent Taylor–Couette flow show, for the first time, experimental evidence of an increase in mixing efficiency at large Richardson numbers.

Modeling urban pollutant transport at multiple resolutions: impacts of turbulent mixing [PDF]
Atmospheric Chemistry and PhysicsAir pollution in cities impacts public health and climate. Turbulent mixing is crucial in pollutant formation and dissipation, yet current atmospheric models struggle to accurately represent it.

Dispersion and Mixing in Quasigeostrophic Turbulence
Physical Review Letters, 2004 The dynamics of passive Lagrangian tracers in three-dimensional quasigeostrophic turbulence is studied numerically and compared with the behavior of two-dimensional barotropic turbulence. Despite the different Eulerian properties of the two flows, the Lagrangian dynamics of passively advected tracers in three-dimensional quasigeostrophic turbulence is ...

Density fluctuation correlations in free turbulent binary mixing [PDF]
, 1994 This paper is devoted to the analysis of the turbulent mass flux and, more generally, of the density fluctuation correlation (d.f.c.) effects in variable-density fluid motion.
