| 摘 要： | 针对低矮门式刚架结构数值风洞模拟中计算域大小设定的问题进行研究.采用CFX软件作为计算平台对某一典型门式刚架厂房进行CFD数值模拟,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合理的取值范围.建议:计算域高度取6h～7h、计算域宽度取4Ly～5Ly、计算域上游长度取7h～8h、计算域下游长度取14h～16h,h为模型高度.

| Abstract: | Aimed at the low portal-frame structure,the problem of dimensional setting of computational domain in the simulation with numerical wind tunnel was investigated.Taking the software CFX as a computational platform for CFD numerical simulation of a typical protal-framed workshop,several parameters which had influence on the computational accuracy were comprehensively analyzed and their reasonable assignment range was proposed as follows: the computational height was 6h to 7h,the computational width was 4Ly to... |
