Although pipeline is an important asset in the transport of fluids, there are many aged pipelines without proper maintenance or replacement. In particular, underground pipelines cause various accidents every year as they are invisible and difficult to manage. Methodologies have been studied to safely manage such pipelines, but few methodologies have analyzed the effect of accident on adjacent pipe. In this study, the behavior of the fluid emitted in the event of a pipe rupture and its effect on adjacent pipe are analyzed using CFD. The simulation is conducted on the above-ground pipeline where air exists between the pipe, and the maximum impact force applied to adjacent pipe is calculated given the transport fluid, operating pressure, and distance between pipelines. In the case of underground pipeline, the soil-induced effect is qualitatively reflected in the simulation results.

尽管管道是流体输送中的重要资产，但仍有许多老化的管道没有得到适当的维护或更换。尤其是地下管线，由于其无形且难以管理，每年都会引发各种事故。已经研究了安全管理此类管道的方法，但很少有方法分析事故对相邻管道的影响。在这项研究中，使用 CFD 分析了管道破裂时排放的流体的行为及其对相邻管道的影响。模拟在管道之间存在空气的地上管道上进行，并在给定输送流体、操作压力和管道间距的情况下计算施加到相邻管道的最大冲击力。在地下管道的情况下，
