潜坝 meaning in English
ground sills; submerged dike
◇潜坝顶 sill; cill
Examples
- Results show that the computed water level and velocity accord well with measurements , the flow module nearby the submerged dikes obeys the law of hydraulics satisfactorily
验证结果，计算的水位流速与实测值吻合较好；流场模拟结果符合潜坝水流运动的一般规律，令人满意。 - Numerical models are frequently used to simulate water flow in hydraulic engineering . shallow water equations are basic governing equations with assumption of the velocity distribution uniformly in vertical , so they have some limitations on the simulation of some plane flows , such as wind - induced flow , curve river flow and flow nearby the submerged dikes . for above - mentioned reasons , extended shallow water equations are developed by introduction of momentum coefficient , correction of convection and bed resistance in equations of motion
在水利工程中经常需要采用数学模型模拟水流的流态，浅水方程是进行平面流态模拟计算的基本控制方程，但因其忽略了流速垂线分布的不均匀性，在模拟某些平面流态(如风生流动、河湾水流、潜坝等工程附近的流动)时存在一定的局限性。
