| 摘 要： | 于室内燃气泄漏引发的爆炸和火灾事故给居民的生命财产造成了极大的损失,通过浮射流理论和紊流扩散理论对燃气泄漏后扩散情况进行了分析简化,建立了流体力学模型并定义了其边界条件.运用CFD软件对该模型进行了数值模拟,得到了泄漏发生后不同条件下的室内燃气浓度的变化规律,对燃气管道优化和减少火灾具有指导意义. |

| Abstract: | The indoor fire induced by gas leakage causes a lot of property loss and fatalities.In this paper,turbulent diffusion theory and buoyant jets theory are used to analyze and simplify the diffusion behaviors after the gas leakage and found its hydrodynamics model.And the boundary conditions are also defined.The model is numerically simulated by CFD software.In different conditions,the development of indoor gas concentration is gained.It is good for optimization of gas pipelines and reducing fire. |
| Keywords: | gas indoor gas leakage numerical simulation |
