摘要:
为了分析风洞试验中观测到的高层建筑模型尾流有规律的漩涡脱落现象,基于计算流体动力学软件CFX和消息传递接口(MPI),利用局域网搭建了并行计算平台,实现了单台计算机无法实现的高层建筑三维非定常风场数值计算。采用剪应力模型(SST)进行数值计算,捕获到了高层建筑尾流的漩涡脱落现象,并与风洞试验数据做了比较。结果表明,三维非定常计算获得的高层建筑表面风压变化规律,较之三维定常和二维非定常计算所得的风场,能更真实地反映风场流动情况。
Abstract:
In order to analyze the regular vortex shedding phenomena of high-rise building model observed by wind tunnel test, authors first established a parallel computing platform using the general software of computational fluid dynamics CFX and local area network with the message passing interface(MPI)network parallel environments, then, simulated a 3-D unsteady wind field around high-rise building while the simulation couldn't be settled by a single computer. The vortex shedding phenomenawere captured by numerical simulation with shear stress transport(SST)turbulence model. The comparison between numerical simulation and wind tunnel test was given. The results show that the varying rules of surface wind pressure on the high-rise building are acquired through 3-D unsteady simulation, and 3-D unsteady simulation's results are used to predict the wind field more truly than 3-D steady and 2-D unsteady simulations' results.
