均勻紊流度 的英文怎麼說
中文拼音 [jūnyúnwènliúdù]
均勻紊流度
英文
homogeneous turbulence-
The extent of attenuation is proportional to the parameter under some assumptions in open channel flow. the lack of a sound theoretical basis for predicting the behavior of coarse particles means that experiments play a critical role
在明渠二維恆定均勻流條件下,經過適當簡化和假定得到的結果表明,懸移質運動起到減弱流體紊動強度的作用,制紊作用隨參數的加大而增強。The contents and original points of view are as follows : 1. the complete depth - averaged tubulence model is adopted to compare with the tradional depth - averaged model. the non - uniformity of velocity in z axis is considered in the former. the rigid - lid assumption, which was adopted for long time, is discarded, while the transpot equation of kinetic energy of dispersion is introduced. the 2d term ' s distribution of space - time is calculated
論文包含的主要內容及創新點有: 1 、引進了完全深度平均紊流模型,與傳統深度平均紊流模型相比,該模型計入了流速在深度方向分佈不均勻的影響;去掉了深度平均紊流計算中長期採用的「剛蓋假定」 ,同時模型通過引進離散動能的輸運方程,計算了二維離散項的時空分佈。
