本文研究了方柱及其群体在不同的气动干扰布局和不同湍流度下对其平均压力系数分布的影响。试验结果表明:雷诺数的变化对方柱体的气动力特性无明显影响;而湍流度的变化对方柱或柱群的压力分布规律有显著影响。若要避免不利的静态气动干扰影响,柱群的布局应选取合适的间距比。本文结论对城市高层建筑规划具有一定的参考价值。
In this paper, we study the influence of square columns and their groups on the distribution of average pressure coefficient under different aerodynamic interference layouts and different turbulence degrees. The experimental results show that the change of Reynolds number has no significant effect on the aerodynamic characteristics of the square cylinder while the change of turbulence has a significant effect on the pressure distribution of the square column or column. To avoid unfavorable effects of static aerodynamic disturbances, the column group layout should be chosen at a suitable pitch ratio. The conclusion of this paper is of certain reference value to the urban high-rise building planning.
