研究目的:地铁是一个人群密集且与外界联系面较小的地下空间,必须设置空调通风排烟系统,对其内部空气环境及火灾情况下的烟气流动等因素进行全面控制,为此,重点研究和掌握地铁车站内部空气的温度、速度、流动方向等分布情况,为乘客及地铁工作人员提供和创造适宜的环境条件。研究结论:地铁车站内部空气环境模拟分析程序软件TSDI-SCFD1.0,以CFD程序软件为平台和基础,能够实现对地铁车站内部空气状况进行三维模拟分析。通过该软件的研究和开发使CFD技术成功的应用于地铁设计中,弥补了以往地铁环控模拟计算分析软件的缺陷和不足,直观、形象的可视化结果和详尽、具体的分析数据,可以为地铁环控专业设计人员的系统设计及方案确定提供准确、可靠的依据。
Research purposes: Subway is a densely populated underground space with less contact with the outside world. Air-conditioning ventilation and smoke exhaust systems must be installed to fully control the internal air environment and the flue gas flow in case of fire. Therefore, the key points To study and grasp the distribution of temperature, speed and flow direction of air inside metro stations to provide and create suitable environmental conditions for passengers and subway workers. Research conclusions: Simulation software TSDI-SCFD1.0 of air environment inside metro station can realize the 3D simulation analysis of air condition inside metro station with CFD program software as the platform and foundation. Through the research and development of the software, the CFD technology has been successfully applied to subway design, which has made up for the shortcomings and shortcomings of the past simulation softwares for subway environment control. Visual and visualized visualization results and detailed and specific analysis data can be used for subway Environmental control professional designers of the system design and program to provide accurate and reliable basis.
