| 概要 |
The validity has been investigated of the Launder-Reece-Rodi Reynolds stress closure model(LRR model)for turbulence near a water surface. A model test has been performed for an oscillating-grid turbul...ence in a homogeneous fluid with a finite depth. Distortion of the near-surface turbulence has been numerically simulated. The numerical solutions normalized by using the exact solution for the infinite depth have een compared with experimental data. A good agreement is seen between the both. The model analysis also predicts that a strong influence of a water surface on the turbulence is observed over the order of the integral length scale. These results show the LRR model analysis to be effective for the turbulence near a water surface.続きを見る
