摘要
该文基于拥有自主知识产权的带自由液面水动力学数值计算程序HydroFlow?,对绕挺水刚性植物群落的流场进行了三维数值模拟。三维的数值计算采用精细的计算网格,模拟了每株植物周围详细的流场。通过与文献实验数据的对比,验证了程序的准确性和模拟的精度。通过对刚性挺水植物群落存在条件下的水槽流场的模拟分析,探究了不同固体体积分数、不同水深下的尾流平均流场分布特征和床面剪切应力分布特征。
The 3-D numerical simulation of the flow through the emergent rigid vegetation patch is performed using an in-house hydrodynamic modelling package called Hydro Flow？.The accuracy of the numerical model is verified against published experimental data.The characteristics of the flow field and the spatial distribution of the bed shear stress in the wake region are analyzed with different solid volume fractions and water depths.
