Examples
- The effects of tripping annulus on a pipe flow and a channel flow were compared and analysed . it indicated that the effect on both flow are mostly identical
全面比较了入口挡环对管流和渠道流中湍流发展过程的影响，发现两者在多方面均存在着一致性。 - In case of high reynolds number , the turbulence intensity of centreline drifted off its stable course in the sections , where the flow was in the transition
在大雷诺数情况下，在流动处于发展阶段的管长范围内，流动中心处的相对湍流强度在入口挡环作用下偏离了稳定状态。 - The effects of the different tripping size were not alike , 20 % tripping annulus was the best size for a pipe flow to obtain fully developed turbulence in the experiment . 8
不同尺寸的挡环对流动中心处相对湍流强度的影响不同，实验结果表明， 20挡环是形成充分发展圆管湍流的最佳尺寸。 - 3 . based on the wall equation and k - ? model , the variable c ? and the variable lm were used to improve the numerical simulation of pipe flow with the tripping annulus at the inlet
在壁函数和-模型的基础上，采用了变模型常数c _ ( l )和变混合长度l _ m的方法对入口处带有挡环的圆管湍流模拟计算进行了修正。 - With the different tripping annulus at the inlet , a new method of the distance definition from the wall was used to measure 35 mean velocity profiles on seven sections in the pipe length x / d = 125 . 2
采用新的离壁距离标定方法，在入口处设有改变扰动强度挡环的条件下，利用热线仪在管长x d约为125的范围内完成了七个不同管流截面上的35个轴线方向速度分布的测量工作。
