Abstract:
Based on FLUENT 6.1.22 soft platform with Reynolds stress model(RMS), authors implied the computational fluid dynamics(CFD)numerical simulated technology to research mean wind pressure distribution on typical spatial structures, such as dome, catenoid and elliptic hyperbolic paraboloid, as well as the characteristics of fluid influence around the structures. The numerical simulation results were found to have good agreement with the wind tunnel experimental results. The characteristics of wind pressure distribution and the flow field were discussed by considering some parameters, such as wind velocity, wind direction angle, roughness of terrain, scale and rise-span ratio. Finally, based on the structure shape and the regularity of wind pressure distribution, in site category B, the local wind pressure coefficient of every region was gained, which can provide reference for the engineering design.
