Turbulent mixing and heat fluxes under lake ice: the role of seiche oscillations [PDF]

Hydrology and Earth System Sciences, 2018
We performed a field study on mixing and vertical heat transport under the ice cover of an Arctic lake. Mixing intensities were estimated from small-scale oscillations of water temperature and turbulent kinetic energy dissipation rates derived from ...

A Comparison between Statistical Behaviours of Scalar Dissipation Rate between Homogeneous MILD Combustion and Premixed Turbulent Flames

Energies, 2022
Three-dimensional Direct Numerical Simulations (DNS) data has been utilised to analyse statistical behaviours of the scalar dissipation rate (SDR) and its transport for homogeneous methane-air mixture turbulent Moderate or Intense Low oxygen Dilution ...

Thermal Equilibrium Curves and Turbulent Mixing in Keplerian Accretion Disks [PDF]

, 1999
We consider vertical heat transport in Keplerian accretion disks, including the effects of radiation, convection, and turbulent mixing driven by the Balbus-Hawley instability, in astronomical systems ranging from dwarf novae (DNe), and soft X-ray ...

Mixing in T-junctions [PDF]

, 1996
The transport processes that are involved in the mixing of two gases in a T-junction mixer are investigated. The turbulent flow field is calculated for the T-junction with the k- turbulence model by FLOW3D.

Atlantic Ocean Heat Transport Enabled by Indo-Pacific Heat Uptake and Mixing [PDF]

, 2019
The ocean transports vast amounts of heat around the planet, helping to regulate regional climate. One important component of this heat transport is the movement of warm water from equatorial regions toward the poles, with colder water flowing in return.

Quality Measures of Mixing in Turbulent Flow and Effects of Molecular Diffusivity

Fluids, 2018
Results from numerical simulations of the mixing of two puffs of scalars released in a turbulent flow channel are used to introduce a measure of mixing quality, and to investigate the effectiveness of turbulent mixing as a function of the location of the

Statistical Mechanics-Based Surrogates for Scalar Transport in Channel Flow

Fluids, 2021
Thermal hydraulics, in certain components of nuclear reactor systems, involve complex flow scenarios, such as flows assisted by free jets and stratified flows leading to turbulent mixing and thermal fluctuations.
