【摘要】 利用计算流体力学软件Fluent,采用Realizableκ-ε湍流模型及混合网格划分方法,对大跨度非对称储煤结构风压分布特征进行了分析研究。结果表明:混合网格划分方法可以实现"由较少的计算量换取精确的计算结果";对于轻型屋面的大跨度储煤结构,堆煤工况引起的风荷载体型系数的变化对结构安全的不利影响不应被忽略。更多还原

【Abstract】 The CFD calculation software—Fluent is used to study on the wind pressure distribution of the long-span asymmetric coal-storage in this paper.Realizable k-εand mixing mesh generation method were used during calculation.The results indicate that mixing mesh method could get accurate results by less calculation.For light roof long-span coal-storage structure,the adverse effects to the wind load shape coefficient which caused by coal could not be neglected.更多还原
