1.
Turbulence characteristics of non-uniform flow in a smooth open channel;
光滑壁面明渠非均匀流水力特性
2.
Based on experimental data measured with a Preston tube,bed shear stresses in uniform and non-uniform flows in open channels were compared under different hydraulic conditions.
在分析Preston管量测试验资料的基础上,对比了明渠均匀流和非均匀流的底壁切应力在不同水力条件下的规律,指出断面中心处底壁切应力、平均底壁切应力和切应力的分布等几个切应力公式在均匀流时适用,在非均匀流时不全适用。
3.
Results of the flume experiments on non-uniform flow over a rough bed show that the vertical distribution of velocity on a channel section needs to be divided into two regions with different log velocity distribution equations.
粗糙床面非均匀流的水槽试验表明,非均匀流断面的垂线流速分布需用两个对数公式分别描述;粗糙床面的流速分布较光滑床面不均匀;非均匀流的紊流度分布随相对水深的增大而趋于均匀;粗糙床面非均匀流糙率系数的变化规律与光滑床面近似。
5)  Nonuniform flow
非均匀流
6)  Non uniform flow
非均匀流
1.
Through the water jet device made by ourself, the flow structure and the deformation of riverbeds of non uniform flow caused by water jets, the mechanism of “Scouring Sediment by Wate Jets” and optimum parameters of water jets in engineering application have been studied in an experimental flume.
泥沙清淤技术及其基础研究需要不断发展,通过自制射流发生装置,在水槽中对射流引起的非均匀流水面比降及垂线流速分布全河段变化特点进行了系统试验研究。
补充资料:非均匀表面
分子式:
CAS号:

性质:实际的固体表面。所有实际的固体表面都不是完全均匀的,如晶格结构会发生缺陷、催化剂的活性组分以大小不同的原子簇的方式分布在表面上,构成活性不一样的活性点,相应的吸附热的大小也是不同的。
