| 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. |
