The present study deals with the shedding process of the Kármán vortices at the trailing edge of a 2D hydrofoil at high Reynolds numbers. Investigations are performed in order to evaluate the ability of an unsteady numerical simulation to accurately reprod ...
We performed combined in situ measurements of bottom boundary-layer turbulence and of diffusive oxygen fluxes at the sediment-water interface in a medium-sized mesotrophic lake. The turbulence was driven by internal seiching with a period of 18 h. This per ...
Combined in situ measurements of bottom boundary-layer turbulence and the diffusive oxygen fluxes at the sediment water interface were conducted in a medium-sized lake. The internal seiche driven periodic forcing produced an oscillatory boundary layer feat ...
The study of turbulent flows has always been a challenge for scientists. Turbulent flows are common in nature and have an important role in several geophysical processes related to a variety of phenomena such as river morphology, landscape modeling, atmosp ...
The turbulent dynamics and stratification of bottom boundary layers, as well as the net diapycnal buoyancy flux in the deep water, have been observed to vary strongly among lakes. The most relevant parameters governing the different regimes are the bottom ...
This paper focuses on the impact of an oscillating low-speed current on the structure and dynamics of the bottom-boundary layer (BBL) in a small stratified basin. A set of high-resolution current profile measurements in combination with temperature-microst ...
