| 1. | Numerical simulation on unsteady flow with turbulence intensity effects in a turbine stage 涡轮级内湍流度影响的非定常数值模拟 |
| 2. | In annular space , the values of tangential , axial and radial turbulence intensity were of the same order of magnitude 环形空间3个速度分量的湍流度是同一个数量级的。 |
| 3. | The turbulence intensity is the result of space variation and temporal variation of particle velocity 颗粒速度的紊动强度为速度的空间变化和时间变化共同作用的结果。 |
| 4. | The axial velocity , fluctuation velocity , the turbulence intensity , and transverse velocity of the fine particle were studied 研究了管道中近壁区颗粒的轴向速度、湍流强度和径向速度。 |
| 5. | The turbulence intensity of particle velocity decreases when particle size or re increases and increases with the increase of fr 颗粒紊动强度随粒径的增大而减小,随fr的增大而增大,随re的增大而减小。 |
| 6. | The existence of a log - law in the centreline velocity profile and the variation of the turbulence intensity in the centreline were discussed in detail 进一步探讨了轴线速度分布中对数定律的存在和轴线上相对湍流强度的变化情况。 |
| 7. | Results show that the longitudinal velocity distribution fluctuates significantly , and that the relative turbulence intensity and reynolds stress have a little increase 结果表明,布设种植圈后,纵向流速分布波动明显,相对紊动强度和雷诺应力均略有增加。 |

| 9. | In some areas , such as the entrance of annular space , vicinity of the roof of annular space , vicinity of the wall , the distributions of turbulence intensity varied sharply , and turbulence was strongly anisotropic 环形空间入口处、近壁和顶部附近的湍流度变化非常剧烈,呈现强烈的各向异性。 |
| 10. | The results showed that the turbulence intensity and turbulent energy of the two - phase flow increased while the transverse velocity decreased in the presence of the temperature difference 分析已有实验数据表明:在温度场存在的气粒两相流中,两相流场的湍流强度和湍动能将会增加而横向速度将会减小。 |
