【摘要】 体育馆防排烟系统性能不同,对火灾燃烧产生的热烟气运动影响也不同,使用CFD技术研究某体育馆防排烟系统的性能。通过数值模拟,给出了不同防排烟系统设计下,火灾发生时的馆内流场和温度分布。在此基础上,分析了各防排烟系统的性能特点。更多还原

【Abstract】 Different performances of smoke evacuation system in gymnasiums have different influence on smoke movement when fire happens.The performance of smoke evacuation system is studied by CFD.With the numerical simulation,we obtain the curves reflecting smoke velocity and temperature varying in the gymnasium.Lastly the conclusions about the characteristic of each smoke evacuation system are made.更多还原
