Turbulent Kinetic Energy(湍流动能)是流体力学中的一个关键概念,用于衡量流体在湍流状态下的紊乱强度和能量耗散速度。
It has long been believed that most turbulent kinetic energy (TKE) dissipation occurs in the near-wall region between ejection and sweep events, i.e. beneath near-wall quasi-streamwise (Q-S) vortices, where wall-normal velocity fluctuations are locally zero. Contrary to this view, our ...
TKENocturnal boundary layerStabilityStationarityIntermittencyYear round measurements of turbulence were taken at heights, above, below, and in the live crown in an old-growth forest in Howland, ME. A technique to determine the stationarity of turbulence kinetic energy (TKE) is presented and used as...
I am exporting the turbulent kinetic energy (TKE) from STAR, and I also am running a wind tunnel experiment on the same model. However, the TKE for the experiments is much much bigger of the order of one order of magnitude. I was wondering if any scaling in STAR causes this. I would...
Turbulent kinetic energy (TKE) is a measure for unsteady loads and important regarding the design of e.g. propellers or energy-saving devices. While simulations are often done for a double-body, using a symmetry condition, experiments and the final product have a free surface. Simulations with...
Improvements in the calculation of turbulent kinetic energy (TKE) by the Mellor-Yamada-Janjic (MYJ) turbulence closure scheme in the Weather Research and Forecasting (WRF) model are presented with a focus on turbulence as measured by the offshore measurement platform in the North Sea, FINO1. ...
