摘要
采用数值模拟方法对井冈山机场航站楼屋盖结构在近地风作用下的表面风压进行了计算,并在边界层风洞中对该屋盖的表面风压进行了模型试验测定。数值模拟基于稳态的Reynolds时均Navier-Stokes方程,运用了标准k?ε湍流封闭模型。将计算得到的风压系数值与风洞试验值作了比较,结果表明数值模拟较好地反映了大跨度屋盖表面风压的分布情况,由其得到的风压系数与风洞试验数据有较好的吻合。
Numerical simulation is carried out to predict wind-induced pressures on the roof of Jinggangshan Airport Building. A boundary layer wind tunnel test is also conducted to measure the induced pressures. The simulation is based on the Reynolds-averaged Navier-Stokes equations and the standard κ-ω turbulence enclosure model is used. The performance of the numerical procedure is evaluated by comparing the predicted wind pressure coefficients with the wind tunnel test results. It is found that the numerical simulation well captures the physical trends of wind pressure distribution and overall good agreement is reached between the computed wind pressure coefficients and the corresponding test results.
