| 摘 要： | 对两种不同负荷条件时给定尾水管非均匀进口速度条件，进行了内流计算流体动力(CFD)分析，采用定常流动计算方法对同一问题进行了对比，给出了两种工况条件下，各主要特征截面上的参数变化特征和详细细节，计算分析结果显示A工况速度条件的流动特征明显优于B工况，解决了CFD非均匀进口速度条件下的给定问题．

| Abstract: | The internal flow of a draft tube was simulated under two different conditions by using the steady flow model and non-uniform inlet boundary conditions by CFD software. Distributions of some flow parameters of computational results on the specific sections of draft tube under two different inlet conditions were compared and analyzed. The simulated results showed that the distribution of flow velocity at point A was much better than at point B. The problem of non-uniform velocity condition on inlet of draft tube could be solved. |
