| 中文摘要 | 论文探讨用并行计算方法求解河道浅水流动和污染物扩散输移,通过建立并行计算系统工作站机群和采用分步有限元格式对河道水污染问题进行求解,得到了河道内流速和污染物浓度分布。通过将明渠污染物侧向排放问题的计算结果与Mikhail等人的试验数据进行比较,验证了本文并行计算模型的可靠性。并对并行计算的效率和加速比进行了分析,从而显示了并行计算技术对于提高计算速度的潜力。选取了涪陵江段的典型排污口,对建库前后的污染混合区进行了预测,分析了计算结果的合理性; The shallow water equations and the pollutant transportation equations are solved by parallel computing technique.By establishing the cluster of workstation(COW)for parallel arithmetic system and using the fractional step finite element scheme,the numerical simulations of river flows and water quality are carried out.For the verification of the model,the results are compared with that of Mikhails.The efficiency and speed up of the present parallel algorithm is evaluated.The numerical model is applied to simulate the pollutant side discharge in an open channel flow.The mixing zones of main discharge outlet at Fuling reach before and after the construction of Three Gorges Project are predicted.The results show that the pollution mixing zones will be increased after the dam is built.; 国家自然科学基金项目 (50 3790 2 2,599790 1 3) |
