圆柱形剧院夏季气流组织数值研究
Numerical study of air distribution of cylindrical theaters in summer
摘要：
针对圆柱形剧院的观众区结构及剧院空调夏季工况特点，利用Chen-Kim K-ε湍流模型和Boussinesq假设研究了不同送风角度和送风温度下剧院的气流组织特性，通过分析比较剧院内温度、速度和流线分布差异，发现送风角度为10°、送风温度为19 ℃时剧院内的速度和温度场分布较为合理，同时气流卫生程度较好。
Abstract：
According to the audience area structure and air conditioning characteristics in summer in cylindrical theaters, investigates the air distribution with different supply air temperatures and angles in summer based on the Chen-Kim K-ε turbulent model and Boussinesq approximation. Analyses and compares the differences of temperature, velocity and flow distribution with different supply air temperatures and angles. Finds that both the temperature and velocity achieve reasonable distribution and the cleanness of air could be well controlled when the supply air temperature and angle is 19 ℃ and 10° respectively.
