摘要
采用计算流体力学(CFD)方法对某发电厂球形穹顶的煤仓周围的风场进行了数值模拟。计算了半球形结构的风荷载,并与实验数据进行对比,证明了该方法用于此类计算的可靠性。同时,还对双仓没有输煤栈桥以及双仓有输煤栈桥的情况进行了模拟,并对三种情况计算的到的煤仓表面的风压分布进行了比较。
In this paper,the computational fluid dynamics was used to make a merical simulation for the wind field around a coal bunker with a spherical vault in a power generation plant. The wind load of semi-spherical structure was calculat- ed, and the practical data was compared with the experimental data, indicating that this method is reliable to be adopted in this kind of calculation. At the same time, simulations were made for the double bunkers without a coal belt conveyor gallery and double bunkers with a coal belt conveyor gallery, and a comparison was made for the wind pressure distribution on the coal bunker surface calculated under three kinds of conditions.
