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
The above researches primarily focus on low-order statistical quantities, such as mean velocity, Reynolds stress, and energy spectrum, but they do not cover higher-order statistics like the turbulent kinetic energy (TKE) budget. In this paper, we conduct a comparative analysis of two numerical sc...
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...
Therefore, the goal of the current work is to characterize these mechanisms in rectangular supersonic jets by directly evaluating their contributions in turbulent kinetic energy (TKE) budget equation. The budgets are obtained using high-fidelity Large Eddy Simulations that employ WALE subgrid-scale ...

In this work, the statistical behaviours of the terms T1 to T6 of the turbulent kinetic energy transport equation, both in the near-wall region and away from the wall, are analysed based on a three-dimensional DNS database of HOI of statistically planar flames propagating across TBLs towards ...

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-...

It can be easily extended to include all the terms of the turbulent kinetic energy budget. In additi...
The kinetic energy budget revealed that the pressure diffusion term of the turbulent kinetic energy budget equation supplied energy to the jet from the mean background flow at the self-similar region of the jet. Introduction Turbulent jet is a subject matter of enormous interest due to its ...
