摘要
以某音乐厅为例,本文利用k-εCHEN紊流模型对某音乐厅使用多种送风方式下的气流组织进行了数值模拟,针对楼座及池座区气流组织的特点,通过改变舞台区侧送风角度优化音乐厅送风条件,获得不同送风角度组合下舞台区温度和速度分布的变化规律,发现舞台区送风口的送风角度分别为9°、11°和11°时气流组织达到最优组合,在此基础上分析了该最优条件下楼座及池座的温度和速度分布特征,为空调设计方案提供参考。
The k-εCHEN turbulence model was used for numerical simulation of air distribution in a concert hall where multiple air supply methods were applied. With respect to the characteristics of air distribution in balcony and stalls, the varying pattern of temperature and velocity distribution in stage area with different combinations of air supply angle was obtained by changing the sidewall air supply angle in stage area to optimize air supply condition of the concert hall. The results showed that the air distribution reached its best combination when the air supply angle of air distributor in stage area was 9°, 11° and 11 °, respectively. The characteristics of temperature and velocity distribution in balcony and stalls in the optimal condition were then analyzed. The findings provide a reference for air conditioning design.
