Evolving Interior Mixing Regimes in a Tidal River Plume

Geophysical Research Letters, 2022
Microstructure profiling was utilized to estimate vertical mixing (via vertical turbulent buoyancy flux) during a tidal pulse in the interior Merrimack River plume in calm winds.

Turbulent mixing layers in supersonic protostellar outflows, with application to DG Tauri [PDF]

, 2015
Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the ...

Simulated mixing in the UTLS by small-scale turbulence using multi-scale chemistry-climate model MECO(n) [PDF]

Atmospheric Chemistry and Physics
The chemical composition of the upper troposphere and lower stratosphere (UTLS) plays an important role for the climate by affecting the radiation budget. Small-scale diabatic mixing like turbulence has a significant impact on the distribution of tracers

Drizzle formation in stratocumulus clouds: effects of turbulent mixing [PDF]

Atmospheric Chemistry and Physics, 2016
The mechanism of drizzle formation in shallow stratocumulus clouds and the effect of turbulent mixing on this process are investigated. A Lagrangian–Eularian model of the cloud-topped boundary layer is used to simulate the cloud measured during flight

Turbulent mix experiments [PDF]

, 1995
Hydrodynamic instabilities produce material mixing that can significantly degrade weapons performance. We investigate the Richtmyer-Meshkov (RM) and Rayleigh-Taylor (RT) instabilities in the turbulent regime in two experimental venues. RM experiments are conducted on the Nova laser with strong radiatively driven shocks (Mach > 20) in planar, two fluid ...

Turbulent Mixing in the Interstellar Medium -- an application for Lagrangian Tracer Particles

, 2008
We use 3-dimensional numerical simulations of self-gravitating compressible turbulent gas in combination with Lagrangian tracer particles to investigate the mixing process of molecular hydrogen (H2) in interstellar clouds.

Turbulent mixing and beyond [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
Turbulence is a supermixer. Turbulent mixing has immense consequences for physical phenomena spanning astrophysical to atomistic scales under both high- and low-energy-density conditions. It influences thermonuclear fusion in inertial and magnetic confinement systems; governs dynamics of supernovae, accretion disks and explosions; dominates stellar ...

Initial conditions for turbulent mixing simulations

Condensed Matter Physics, 2010
In the context of the classical Rayleigh-Taylor hydrodynamical instability, we examine the much debated question of models for initial conditions and the possible influence of unrecorded long wave length contributions to the instability growth rate α.
