摘要
提出非规则网格有限体积法计算复杂外形体育馆建筑的室内气流分布.采用κ-ε湍流模型进行分析,在建筑地面与壁面考虑了气流流动粘性作用的影响,用壁面函数加以修正.据此,编制了通用计算程序,计算分析了体育馆建筑室内气流分布方案,找到最优方案,为空调设计的优化提供了强有力的分析手段.
The irregular, grid finite-volume method is developed for computing air flow distribution of gymnasium with complex geometries building. The turbulence is described by the k- e modes with wall function near solid boundaries. The computing procedure is used to sedate airflow distribution in gymnasium with complex geometries. The result shows that the numerical method is available for this issue.
