摘要:
举办大型运动会期间，火炬塔燃烧产生的热量可能会对周围物体产生不利影响，一般需要进行安全评估。利用消防安全工程学原理，提出了大型运动会火炬塔安全评估方法，建立了各个分析对象的安全判定标准；采用CFD（计算流体动力学）软件，对某运动会期间主火炬塔燃烧对周围物体的影响进行了数值仿真；通过对火炬塔燃烧状况、环境条件和周围物体进行具体分析，遵从最不利原则，建立了5个计算场景，分析了在主火炬塔燃烧产生热量的作用下，周围LED显示屏、威亚、看台膜材料的温升，根据预先设定的安全判据，可以判断出周围物体均处于安全状态
Abstract:
When holding large games, the heat produced by the torch tower may possibly influence surrounding objects . When temperature of the object exceeded the allowable value, the object would become invalid.So safety assessment for effect on the surrounding objects of the torch tower need to be taken. According to the principle of fire safety engineering, a safety assessment method of the torch tower was presented , and the safe criterions of the surrounding objects heated by the torch tower were discussed. In this paper ,CFD（Computational Fluid Dynamics）software was used to simulate the effect of torch tower. By studying the combustion conditions and environmental conditions of the torch tower, five computing scenes were identified. The temperature rising of LED display, wire and membrane materials were studied. Numerical simulation results showed that the maximum temperature of LED display is 64℃，the maximum temperature of wire is 142℃ and the maximum temperature of wire is 44℃.According to the safety criteria, we can judge that surrounding objects of the torch tower is safe.
