摘　　要：采用k-ε湍流模型对某演艺中心的室内气流组织问题进行了数值模拟.研究了夏、冬及过渡季三个季节场馆内空气温度场和速度场的分布特征.在此基础上,通过改变送风口角度和送风风速,研究了不同工况下大空间的气流组织,探讨了大型室内环境的改善与优化控制问题,提出了室内环境的改善策略与优化方案.In this paper,a k-εturbulence model is used to numerically simulate the indoor airflow organization problem of a performing arts center.The distribution characteristics of the air temperature and velocity fields in the arena during the summer,winter and transitional seasons are studied.On this basis,by changing the angle of air supply outlet and air supply speed,the air distribution in large space under different working conditions is studied,the improvement and optimization control of large indoor environment are discussed,and the improvement strategy as well as optimization scheme for indoor environment are put forward.

关 键 词：大型演艺中心场馆 室内气流组织 数值模拟 温度分布 速度分布
