Simulation and Analysis of Decompression Wave in the Gas Transmission Pipeline
摘要
Abstract
Combined with fluid equilibrium equation model, sound velocity model and gas flow-out model, a decompression wave model was developed. The influence of gas composition, initial temperature and initial pressure were simulated and analyzed by using this model. The results show that decompression wave curve shows a plateau for gas with heavier composition. It is also demonstrated that lower initial temperature and higher initial pressure increase the risk of fracture propagation. And proper equation of state should be chosen for the simulation.关键词
