Wind-Driven Mixing below the Oceanic Mixed Layer [PDF]

open access: yesJournal of Physical Oceanography, 2011
AbstractThis study describes the turbulent processes in the upper ocean boundary layer forced by a constant surface stress in the absence of the Coriolis force using large-eddy simulation. The boundary layer that develops has a two-layer structure, a well-mixed layer above a stratified shear layer. The depth of the mixed layer is approximately constant,

Dynamics of Mixing Layer Height and Homogeneity from Ceilometer-Measured Aerosol Profiles and Correlation to Ground Level PM2.5 in New York City

open access: yesRemote Sensing, 2022
Observations of mixing layer height (MLH), its dynamics and the extent of homogeneity of the mixing layer are important in the study of air pollution as well as meteorological and air quality model validation.

Numerical Investigation of the Effect of Air Leaking into the Working Fluid on the Performance of a Steam Ejector

open access: yesApplied Sciences, 2021
This paper investigated the effect of air leaking into the working fluid on the performance of a steam ejector. A simulation of the mixing of air into the primary and secondary fluids was performed using CFD. The effects of air with a 0, 0.1, 0.3 and 0.5

Impact of a discretization scheme on an autoignition time in LES of a reacting droplet-laden mixing layer

open access: yesArchives of Mechanics, 2021
We analyse an autoignition process in a two-phase flow in a temporally evolving mixing layer formed between streams of a cold liquid fuel (heptane at 300 K) and a hot oxidizer (air at 1000 K) flowing in opposite directions. We focus on the influence of a

Vortex structures evolution in supersonic mixing layers with different inlet Reynolds numbers based on the Lagrangian method

open access: yesAIP Advances, 2021
The supersonic mixing layer is a typical flow structure in an aircraft’s optical seeker. The free incoming flow and cooling jet form a mixing layer through shearing.

Various information and complexity measures for analyzing the laminar-turbulent transition process in mixing layer (Analysis of fluctuating vorticity and turbulent energy dissipation rate)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
In this paper, the laminar-turbulent transition process of a mixing layer downstream of a two-dimensional nozzle exit was analyzed based on various information and complexity measures.

Summertime Urban Mixing Layer Height over Sofia, Bulgaria

open access: yesAtmosphere, 2019
Mixing layer height (MLH) is a crucial parameter for air quality modelling that is still not routinely measured. Common methods for MLH determination use atmospheric profiles recorded by radiosonde but this process suffers from coarse temporal resolution

The Relationship between Contraction of the Ejector Mixing Chamber and Supersonic Jet Mixing Layer Development

open access: yesAerospace, 2022
Supersonic mixing layer development seriously impacts on the performance of an ejector, and the effect of mixing chamber contraction angle on supersonic jet mixing has been poorly studied.

Growth of a Richtmyer-Meshkov turbulent layer after reshock [PDF]

open access: yes, 2011
This paper presents a numerical study of a reshocked turbulent mixing layer using high-order accurate Implicit Large-Eddy-Simulations (ILES). Existing theoretical approaches are discussed, and the theory of Youngs (detailed in Ref.
