基于计算流体力学软件Fluent，对上海市一双塔超高层建筑幕墙周围风场进行数值模拟.较之风洞试验，数值模拟风场的方法具有花费低、周期短、测点布置灵活等优点，因此，这种越发完善的数值仿真技术正进入工程应用的成熟领域.在数值模拟过程中采用雷诺应力方程模型，并充分考虑控制方程、计算模型、边界条件等关键因素，将数值模拟结果与风洞试验数据进行对比，验证数值模拟方法应用在现代商业高层建筑风环境分析领域的可行性与准确性.

This paper studies numerical simulation of the average windload pressure coefficient of super high-rise building cladding using the software Fluent. As compared to the wind tunnel test, the simulation method has the advantages of low cost, short test cycle and flexibility in choosing survey points. The simulation technique is becoming perfect and applied to actual construction fields. This paper discusses how the Reynolds stress equation model is used in the simulation and considers key elements including control equation, calculation matrix, boundary condition, etc. The simulation result is compared with wind-tunnel tests. Feasibility and usefulness of the simulation method is validated.
