The turbulent structure in open channels and pipes is one of the basic problems in hydraulics, In this article special attention has been paid to analyze the flow structure close to the bed on the basis of stochastic theory of turbulent flow developed by the author. It is pointed out that the division of the flow regime into smooth, transition and rough depends on the fact whether the flow passing the roughness element is separated or not. When the Reynolds number is low (ν_*△/ν≤1.25), there is no separation and turbulent flow is in the smooth region. As there is a partial separation. the turbulent flow would be in the trasition region. When the Reynolds number is high (ν_*△/ν≥100), there would be a complete separation and the turbulent flow would be in the rough region. The thickness α△ of separation layer and the velocity v_α at the top of the separation layer are given. By using these boundary conditions a universal velocity distribution law for all three regions is deduced. By integrating the velocity distribution formula over the cross-sectlonal area of circular pipe we can obtain the universal equation to determine the drag coefficient in all smooth, transition and rough regions. In the case of open channel flow an analogical universal drag coefficient formula can be obtained too. In such a way the well-known drag coefficient diagram of Nikuradse has been generalized in theory. All the theoretical formulas obtained are in good agreement with the experimental results reported by various investigators,

Experiments of a dilute salt-water/clay suspension compared with pure water have been made in an open channel of bottom coated with cement. Two kinds of fluid systems all were steady uniform and fully developed turbulent flow in the smooth region. The fluid surface slopes in the channel were measured for Reynolds numbers between 13,500 and 40,000, and the mean time velocity distributions in the core region of turbulent flow were measured by propeller current meter. For the clay suspensions, the results of measurements of the surface slopes and the mean time velocity distributions each and all show that phenomenon of turbulent drag reduction occurs within the ranges of experimental Rey- nolds numbers, The experiments also indicate that drag reduction rate of a dilute salt-water/clay suspension increases with an increasing a- mount of the salt concentration. Under this experimental conditions, the salt-water containing suspended clay particles exhibits a material of lower effective drag reduction in the turbulent flow.

在用水泥抹底的活动玻璃水槽中,进行了含盐稀淤泥悬浮液与自来水的对比试验。两种流体系均为充分发展的恒定均匀的光滑紊流。在雷诺数Re为13500至40000范围内,测量了明渠液面坡降,并用旋桨式流速仪测量了紊流核心区的时均流速分布。液面坡降和时均流速分布的测量结果均一致表明,含盐稀淤泥悬浮液在所试验的雷诺数范围内,出现了紊流减阻现象。试验还表明,含盐稀淤泥悬浮液的减阻率,防雷诺数和含盐浓度的增加而加大。然而,含盐稀淤泥悬浮液在本试验条件下,表现为一种低效的减阻流体。
