摘要
基于紊动水流的基本方程,经模化及垂线平均化后,求解了紊流方程组的数值解,得到了河道障碍物后不同断面上的流速分布。由水流内部流速分布变化的分析。
Based on the N\|S equations,a simple 2\|D algebraic stress model is derived by statistical average method with some assumptions.The numerical value of equations is solved and the velocity distributions in different sections after barrier are obtained.By analyzing the above data,the effect of barrier on turbulent flows is revealed.
