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。
Computational fluid dynamics (CFD) method is used to simulate the wind field around the bunker of a spherical dome of a power plant. The wind load of the hemispherical structure is calculated and compared with the experimental data to prove the reliability of this method for such calculation. At the same time, this paper also simulates the situation that there is no coal conveying trestle in double warehouse and coal trestle in double warehouse, and compares the wind pressure distribution on the coal warehouse surface calculated by the three cases.
