Two Dimensional Analytical Solution for a Partially Vegetated Compound Channal Flow

  • 摘要: 运用涡粘模型理论对部分植被化复式河道的水流水深平均流速和边壁切应力分布进行了求解.通过对水流微元体进行纵向受力分析建立相应的控制微分方程,其中植被对水流的影响归结为拖曳力项.同时将复式渠道划分为3个子区域,通过联立求解各区域微分方程中的定解系数,最终得到均匀流的条件下各区水深平均流速的横向分布的解析解.在获得水深平均流速的横向分布后,可进一步给出对泥沙输移有重要影响的河床切应力的横向分布.通过与试验测得的资料比较,表明给出的解析解能够为工程设计提供足够精度的水力特性的预报.
