研究了横风向风荷载对高耸异形烟囱的作用模式,采用计算流体动力学(CFD)方法对烟囱进行了非定常风场数值模拟,获得了烟囱横风向气动参数。结合某电厂210m高异形烟囱初步设计方案进行了横风向风荷载作用下的动力响应分析。
The effect of crosswind wind load on towering shaped chimney was studied. The CFD method was used to simulate the unsteady wind field of the chimney, and the aerodynamic parameters of the crosswind wind direction of the chimney were obtained. Combined with the preliminary design scheme of a 210m high-profile chimney in a power plant, the dynamic response under cross-wind wind load was analyzed.
