bed resistance meaning in English
河床阻力
Examples
- 4 . the movable - bed resistance problem has been studied
研究了动床床面阻力问题。 - The methods of calculating movable - bed resistance have been studied from two methods
本文采用两种方法研究了动床阻力问题。 - The bed resistance is obtained by express of the single - fluid model for debris flow
数学模型采用一种基于三角网格的显式差分格式?有限节点法。 - 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。 - To meet the necessity of engineering practice , this thesis carries out a research on the flow characteristics of the concrete abatise groups . after summarizing the present methods of bed resistance research , on the base of theoretic analysis , the contents , technical analysis and methods of the research are decided
