The Coupled Analysis of Pipe Burst and Multicomponents Fluid of Very High Pressured Natural Gas Pipeline

摘要

1. The decompression of natural gas is slower than one of ideal gas. 2. The two-dimensional coupled analysis of fluid and structure is developed. 3. The large inertia force continues pipe deformation, although the pressure load on pipe wall is weakened drastically. 4. At the boundary of air and natural gas, large gradient of temperature is observed. 5. The liquefaction of expanded natural gas is observed.
