不淤流速 meaning in English
transportation velocity
velocity to prevent sedimentation
Examples
- Finally , the equations of the velocity when the particles start to move , suspend and stop were gotten from the rule of silt sediment movement . the velocity with no depositting was gotten from a equation of silt sediment movement in drainage
最后又借用泥沙运动方面以及污水管道内泥沙运动方程的知识,得出了不同管径下颗粒的起动、扬动、止动流速与管道运行临界不淤流速。 - Based on the riverbed evolution analyses of the downstream reach of oujiang estuary and physical model test of eight types of regulation projects , an estimation method for nondeposit velocity satisfying channel depth is presented under fixed bed model test condition
摘要通过对瓯江口外段河床演变分析，以及8种航道治理工程的物理模型试验，提出了在定床试验条件下满足航道水深所需的不淤流速的估算方法。 - In this paper , wastewater is looked on as solid - liquid two - phase flow . firstly , the sedimentation of the particles in fluid was analyzed , and some equations was induced under different flow conditions . this set a base for the velocity in the next chapters
本文将污水视为固液两相流,首先对颗粒在流体中的沉降理论进行了分析,从中得出沉降速度在不同流动状态下的表达式,为后面分析颗粒的起动、扬动、止动流速与管道运行临界不淤流速打下了一定的基础。 - And the relation between these velocity was analyzed at last . this is the conclusion : ( 1 ) the distribution of the velocity and concentration are get in the open channel flow and as the sewage flow is gravity flow , the equations is fit for this too . ( 2 ) generally speaking , the self - cleaning velocity should be the starting velocity , and it could fit for the self - cleaning target in limited sense theoretically , but when facing some higher requirement , it is not large enough
最后结合污水流动的最小设计流速与颗粒起动流速、临界不淤流速的关系进行了分析,结论如下: ( 1 )文中所得出的速度分布与浓度分布是在明渠两相流动情况下推得的,由于污水管道流动多为重力流,是明渠流中的一种,所以文中的分析在认识污水流动特性方面具有一定的参考价值。
