摘要
以采空区输气管道为研究对象,把天然气视为可压缩理想流体,利用FLUENT软件研究了温度对于采空区管道内部气体压力的影响,得到了某一天内不同时刻输气管道内压。通过与室温下管道内压的对比,得出输气管道出现最大内压的时刻以及相应的压力分布。在此基础上,研究了最大压力发生时刻输气管道的应力分布。
In this paper,the gas pipeline over mined-out areas is regarded as the research object and the natural gas is regarded as the compressible fluid. The influence of temperature on the pipeline internal pressure is studied using FLUENT software,and the pipeline internal pressure in a day has been reached. Through comparing with the pipeline internal pressure at room temperature,the moment and distribution of the maximum pipeline internal pressure has been obtained. On this basis,the stress distribution at this moment is researched.
