摘要

基于计算流体动力学(CFD)和SST k-ε湍流模型,运用FLUENT软件针对草帽型大跨空间结构表面风压及其规律进行数值模拟和分析比较,运用典型算例分析对比模拟结果与既有文献结果,以验证数值模拟的可信性。系统性研究了结构高跨比等关键参数对草帽型空间结构表面不同部位风压分布的影响。

Abstract

Based on computational fluid dynamics and SST k-ε turbulence model, the wind pressure distribution of Mexico-hat like spatial structures is numerically investigated and analyzed by using FLUENT software. The benchmark problem is used to verify numerical results by comparing the current simulation with the existing research results from related references. The influence of height-width ratio on the wind pressure distribution on different parts of Mexico-hat like spatial structure is studied in detail.
