Numerical simulation of air distribution in large space of a civil air defense work
摘要：
针对某地下人防指挥大厅人员和散热设备分布规律，选取不同的送风口数量、送风口尺寸、送风口布置方式和送风速度，提出了3个设计方案。利用CFD软件对各方案的温度分布、速度分布进行了模拟，确定了合理的送风口位置和最佳的送风参数，得到了满足人体热舒适性要求的设计方案。

Abstract：
According to the distribution characteristics of staff and radiating equipment, selects different number，size and location of air supply inlets and air velocity, and provides three design schemes. Simulates the air temperature and air velocity distribution by CFD software respectively, and finds proper locations of air supply inlets and optimal air supply parameters. Obtains the design scheme meeting the demands of the human thermal comfort.
