Comparison of Numerical and Wind Tunnel Simulation of Wind Loads on Domed Structures in Different Roughness Upwind Areas

摘要

Mean surface pressures and overall wind loads on domes immersed in a boundary layer were obtained by numerical simulation. The effects of alternative turbulence models, upwind areas were examined and compared with wind tunnel studies. Surface pressures on dome structures were calculated in two cases by numerical simulation. One is with surrounding structures to calculate the wind comes from east and west direction, another one is no surrounding structure. The results will be evaluated the accuracy of numerical simulation with different roughness types of upwind area and effect of surroundings. Calculated values were compared to wind-tunnel measurements made in equivalent flow conditions.
