| 中文摘要: |
| 建立了并行计算系统工作站机群，实现了浅水流动的并行数值模拟。采用信息传递接口(MPI)为通讯库，实现了基于图论的区域剖分方法，并且提出了一种显隐交错的数值格式，该格式具有数值计算精度高，适合并行计算的特点。计算了较低雷诺数下（R<300）方柱绕流的情况。并与Suzuki及Breuer的结果进行了比较。 |
| 英文摘要: |
| The cluster of workstation for parallel arithmetic is established to carry out the large scale numerical simulation of shallow water flow. The message passing interface(MPI) is applied. The Delauney triangulation algorithm is used to realize the automatic generation of unstructured mesh and domain decomposition is based on graph based algorithm. A brand new numerical scheme, namely explicit and implicit interleaving scheme(EII), is proposed. The flow around a square column at low Reynolds number(Re<300) is calculated and the result is in good agreement with that of predecessors. |
