港口集装箱群数值模拟中计算域设置的研究

Research on the computational domain setting of the numerical simulation about the harbor container groups

采用计算流体力学数值模拟技术对某港口集装箱群落进行了数值风洞模拟.数值模拟采用良好适应性的非结构化四面体单元进行网格划分.在对影响计算结果精度的各个参数进行综合分析的基础上,提出了港口集装箱群数值风洞模拟中计算域设置合理的取值范围:计算域高度7h^8h,计算域宽度8Ly^9Ly,计算域上游长度9h^10h,计算域下游长度18h^20h.该结论也为群体建筑物计算域的设置提供了参考.

The numerical wind tunnel simulation about the harbor container groups was studied by using computational fluid dynamics numerical simulation technology. Tetrahedral elements with good adaptability were adopted to divide the computational domain. The reasonable computational domain in the numerical simulation of the harbor container groups was obtained based on the analysis of the factors affecting the calculation accuracy. The value range of the computational height is 7 h to 8 h, the computational width is 8 Ly to 9 Ly ,the front length is 9 h to 10 h ,and the back length is 18 h to 20 h. The result can also provide some recommendations to the computational domain setting of the building groups.
