明渠紊流 meaning in English
turbulent flow in an open channel
Examples
- The turbulent flow in open channel is tested with laser - doppler anemometer , in which the longitudinal time average velocity and fluctuating velocity of turbulent flow in open channel under the conditions of the sudden changes of roughnesses at different water depths are measured
摘要通过激光测速仪，对壁面糙率突变时的明渠紊流进行试验，测量了糙率突变不同水深情况下明渠紊流的纵向时均流速和脉动流速。 - A variety of mathematical models based on continuous equation and the momentum equation and many solutions partial differential equation value computational method in the open canal turbulent flow solution , still could widely apply and yield the satisfactory result
但是,非稳态的navier - stokes方程对于明渠水流的瞬时运动还是适用的,以连续方程和动量方程为基础,建立的各种数学模型和许多求解偏微分方程的数值计算方法在明渠紊流的求解中仍能广泛应用。 - This article ’ s purpose is to simulates the apron that adds the coarseness fluent speed of flow in to hang the upward distributed , through the comparison , absorbs other mathematical simulations in model and the method , established the surface two - dimensional current of water mathematical model of apron that adds the coarseness
本文以模拟海漫加糙后明渠紊流的流速在垂向上的分布规律为主要内容,通过比较、借鉴其它数学模拟的建模方法,建立了海漫加糙后水流垂向二维数学模型。 - In the turbulent flow , the fluid ’ s physical parameters has the stochastic change along with the time and the space , it is very difficult to carries on its rate process ’ s precise computation and the simulation with mathematics method , but unstable condition navier - stokes equation regarding open canal current of water transient motion suitable
闸后水流经过加糙的海漫段时,其水流状态属明渠紊流。流体中的各种物理参数,都随时间与空间发生随机的变化,很难用数学的方法对其运动过程进行精确计算和模拟。
