turbulent boundary layersturbulent flowsThis paper examines the Reynolds number ( $Re$ ) dependence of a zero-pressure-gradient (ZPG) turbulent boundary layer (TBL) which develops over a two-dimensional rough wall with a view to ascertaining whether this type of boundary layer can become ...
Usually, large-eddy simulation (LES) models are used to study rather idealized atmospheric boundary layer flow situations. However, more realistic turbulence fields are of great interest for example for wind engineering or environmental applications. To make a step towards less-idealized flows, processe...

Experiments in a boundary layer subjected to free stream turbulence. Part 2. The role of TS-waves in the transition process The natural occurrence of Tollmien-Schlichting (TS) waves has so far only been observed in boundary layers subjected to moderate levels of free stream turb... AV Boiko,...
Natural inputs of oxygen to the ocean are restricted to the sunlit, surface layer of the ocean where photosynthesis can outpace respiration and where oxygen can be taken up from the atmosphere. Once transported beneath this surface layer, oxygen is progressively consumed by aerobic respiration. The...
Under a Creative Commons license open accessHighlights Abstract Before particulate matter that settles as ‘primary flux’ from the interior ocean is deposited into deep-sea sediments it has to traverse the benthic boundary layer (BBL) that is likely to cover almost all parts of the seafloor in ...
2c), the effect of tides can reach the top of the atmospheric boundary layer (in the example shown, a stable layer of about 800 m) with a positive temporal correlation between currents and winds (>0.7 over a week). Above the atmospheric boundary layer, the correlation between currents and...
A 30-min averaging period is used for the Reynolds decomposition, a common choice for atmospheric boundary layer calculations47,48. We classify stable conditions for 0m<L≤200 m (0<z/L≤0.02), unstable conditions for −200m≤L<0 m (−0.02≤L<0), and near-neutral otherwise. As ...
