摘要
为研究桅杆结构的气动参数,采用大涡模拟(LES)方法对某桅杆结构进行了三维非定常风场数值模拟,获得了桅杆结构的阻力系数、升力系数和斯脱罗哈数,为桅杆结构风荷载响应分析提供了合理的气动参数。同时,对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。
Large Eddy Simulation(LES) method is employed to investigate aerodynamic parameters of a guyed mast. Drag coefficient, lift coefficient and Strouhal number are obtained by numerical simulations and the results can be used for study on aerodynamic responses of the guyed mast. 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.
