摘要
射流风机是纵向排烟系统的主要装备。近年来,其在地下车库及大空间诱导排烟系统设计中得到应用并成为研究热点。依据DA-1AT型射流风机速度场实验测试数据,采用与火灾动力学速度场模拟结果比较的方法,验证了FDS在模拟射流风机速度场方面的适用性和可信性。分析研究了FDS网格独立性问题,给出了DA-1AT型射流风机模型建议尺寸和FDS网格尺寸,可以为射流风机流场分析提供参考。
Jet fan is the main equipment in longitudinal smoke exhaust system. In recent years, jet fan smoke exhaust system design has been used in the underground garage and large space and thus become a re- search focus. By comparing the test data of speed field with that of the speed field of fire dynamics （FDS） simulation, this paper analyzes grid independence of FDS and gives grid size for DA-1AT jet fan. To ensure consistence of the simulation results with the measured results, the simplified size of jet fan is adjusted for the final simulation. The paper is of value to jet fan flow field analysis.
