针对建筑物复杂外形的结构特点,创建了贴体网格生成方法和基手同位网格的数值模拟算法。在通过与实验进行对比验证的基础上,数值模拟了不规则屋顶建筑物、大型体育馆等复杂外形建筑物内的气流组织分布。研究结果表明:所提出的基于贴体网格的同位布置算法及其计算程序具有较好的通用性,能用于各种不规则几何形状空调建筑内气流组织的数值模拟研究。%In light of complicated features of external building structure, the paper creates body-fitted grid generation method and numerical simu- lation algorithm based on non-staggered grid. Based on comparative test with experiment result, the body-fitted grid numerically simulates the air stream organization and distribution of complicated external buildings including building with irregular roof and large-scale gym. Results show that the body-fitted grid algorithm and its calculation program has better generality, and can be used for numerical simulate research of internal air stream of various irregular external building structure.
