摘要

为研究高耸异型烟囱横风向气动参数,采用计算流体动力学(CFD)方法对某发电厂烟囱进行了非定常风场数值模拟,获得了烟囱各典型剖面的侧力系数均方根和斯脱罗哈数,为烟囱横风向风振分析提供了合理的气动参数。同时,对与该烟囱剖面形式相近的经典钝体绕流问题进行了数值模拟,所得结果与实验及前人数值结果吻合良好,验证了方法的可靠性。

Abstract

Computational fluid dynamics (CFD) method is employed to clarify across-wind aerodynamic parameters of special-shaped tall chimney. RMS value of lift coefficient and Strouhal number are obtained by CFD simulation and the results can be used for study on across-wind vibration of the chimney. In addition, the flow around a square cylinder and the flow around a circular cylinder are studied, and the results are compared with the data obtained from the wind-tunnel experiment.
