查询词典 turbulence

A high-speed camera is used to visualize the flow structures,and Laser Doppler Velocity is employed for velocity measurement.The osculations are conducted on the two-dimensional hydrofoil section,based on a single-fluid model of the cavitation:the liquid/vapor mixture is considered as a homogeneous fluid whose eompsition is regulated by mass tranfer equation.The RNG k-ε turbulence model with modified eddy viscosity coefficient is used for computing,and the coefficient is related to the vapor and liquid densities in cavitated regions for simulating the cavitating flow.

实验采用高速录像技术观察了云状空化随时间的结构变化，应用 LDV 测量了云状空化条件下翼型周围的速度分布；采用 N-S 方程和基于空泡动力学方程的空化模型计算了绕水翼云状空化流场，湍流模型采用了 RNG k-ε方程，为了改善空化流动的计算精度，引入了一种与空化区域水汽相密度相关的系数，对湍流涡黏性系数进行了修正。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
