1)  turbulent structure near the wall
近壁湍流结构
2)  near-wall turbulence
近壁湍流
1.
And statistic characteristic of near-wall turbulence is researched.
在此基础上,采用剪切修正亚格子模型的大涡模拟(LES)的方法,模拟了不同雷诺数下的槽道湍流,研究了近壁湍流的统计性质,进而在壁面加入吹吸,研究了空间周期的湍流场中雷诺应力和速度变形率之间的相位关系。
3)  Turbulence structure
湍流结构
1.
The turbulence structure control by adding component parts similar to the large eddy break up device and riblets in the hydrocyclone was investigated by studying the characteristics of the turbulent pressure field,and the relationship between turbulence structure variation and energy consumption reduction was also studied.
本文将采用设置类似大涡破碎器和流向棱纹面的方法,对旋流器内的湍流结构进行控制,并研究其湍流结构的变化与能量耗损降低的关系。
2.
These results show that turbulence structure generated by tumble has the characteristics of larger scale and lower frequency, and therefore autocorrelation coefficient and intergal time scale of turbulence are considerably increased when tumble breaks up at the end of compression.
本研究在一台四气门汽油机上对缸内滚流运动进行了LDA测量,通过改进测试系统提高了数据率,用低通滤波的单一循环分析法计算了湍流结构参数。
3.
As a cure of this shortcoming, it is suggested that the traditional ASM could be corrected to be a K-E LAASM, in which the boundary conditions of turbulence structure can be specified independent of the mean velocity profile and turbulence intens.
为此本文提出一能独立加入有关湍流结构的边界条件的K-ELAASM,问题得到圆满解决。
4)  turbulent structure
湍流结构
1.
