point velocity meaning in Chinese
点流速
点速度
Examples
- Validation of the observing velocity data in different channels indicates that the velocity distribution law given by authors is in accordance with the real velocity - distribution perfectly in open channel ; and the relative error between observing value and calculating value of point velocity is small , which can satisfy the precision requirement in the calculation of velocity distribution and discharge in open channel
采用不同管道流速资料进行验证，表明所提出的明渠流速分布律与实际分布一致，对应测点流速相对误差较小，可以满足明渠流速分布及流量计算精度要求。 - At first , in the process of experiments , it were measured that dry plate pressures drop and point pressures in the flow fields around the single fixed - valve and double fixed - valves under different velocities by using of pitot tube . after that point pressure was transformed to point velocity , two dimensions flow plane of flow fields around fixed - valve were plotted to observe the difference between of the fixed - valve tray with fold edges and the common rectangular fixed - valve tray on the distributions of flow fields and pressures , to provide comparisons and refer - rence for cfd simulation
在实验中，利用测速管等仪器对在不同速度下的单阀和双阀固定阀周围的流场进行了点压力测量，然后把点压力转化为点速度后绘出固定阀周围流场的二维流线图，同时测定了塔板的干板压降，来考察新型固定阀带折边后对流场分布和压降的影响，为随后的数值模拟提供对比和依据。
