某剧场室内热环境CFD模拟分析

Interior Thermal Environmental Analysis of the Theatre with CFD

空调系统形式对于高大空间剧场的室内环境具有决定性影响,为验证空调系统形式的合理性,在设计阶段采用模型实验是不现实的,而CFD模拟是一种成本低、速度快、资料完备的有效方法;采用计算流体力学模拟软件STARCD对某剧场夏季和冬季室内热环境进行模拟,根据模拟结果,分析了空调系统设计方案的合理性,并提出改进建议。

The air distribution pattern plays a crucial role in determining the indoor environment quality of atrium-type spaces such as a theater. CFD becomes a low-cost,speedy and effective method to validate the proper design of air distribution, as it is impractical to measure and verify with physical models. This paper summarized the procedure of simulating the airflow pattern of a theater under cooling and heating conditions,using STAR-CD,one of the three most used commercial fluid software package in the world. The simulation results lead to design optimization for the air distribution,which is taken into account of the re-simulation after the design adjustment.
