Kinetic energy budgetIn high flow velocity areas, turbulence intensity is high and flow variations may have a major impact on tidal turbines behaviour. Previous studies show that a square wall-mounted cylinder produces a very extended and energetic wake. In this work, two-component PIV measurements...
As an important physical process at the air-sea interface, wave movement and breaking have a significant effect on the ocean surface mixed layer (OSML). When breaking waves occur at the ocean surface, turbulent kinetic energy (TKE) is input downwards, and a sublayer is formed near the surfa...

The one-dimensional equation for the turbulent kinetic energy budget in steady, horizontally-homogeneous flow near the ground is reviewed, and some of the many experimental evaluations of its stability-dependent terms obtained during the last twenty years are compared. Uncertainties attributable to instru...

However, contributions to the TKE budget by vertical advection and vertical shear generation, as well as the tendency of TKE can be estimated by calculating forward differences in space and time respectively. From now on AD and S will always refer not to the total but to the vertical portion...
Turbulent kinetic energy (TKE) budget variations during thunderstorm days (TD) and nonthunderstorm days (NTD) of premonsoon seasons of 2007, 2009, and 2010 have been investigated at a tropical station Kharagpur (22°30′N, 87°20′E) using the surface layer turbulence data obtained during seve...
Extension of the OpenFOAM's pimpleFoam solver to calculate the total (SGS + resolved) turbulent kinetic energy and turbulent dissipation rate at runtime during LES simulations. It can be easily extended to include all the terms of the turbulent kinetic energy budget. In addition, the LES resolu...
Careful inspection of the turbulent kinetic energy budget reveals that the opposite rotational sense of the secondary flow between the ridge- and strip-type roughness elements is primarily attributed to the local imbalance of energy budget created by the strong turbulent transport term over the ridge-...
