Study on the Risk of Unsteady Leakage and Explosion of Long Gas Pipeline

摘要：

Through analyzing the process of unsteady leakage of long gas pipeline, the calculating model of unsteady leakage ratio has been founded. Based on the differential equation of turbulent model, original and boundary conditions, the diffusion model of unsteady leakage of gas pipeline has been established by using Green Function. Then, the damaging and destroying modeles of leakage and explosion have been established. Based on certain conditions, the damaging and destroying areas of leakage and explosion have been discussed. It will provide safety standards and references for confirming and formulating the safety distance of buildings near main gas pipeline in city. At the same time, it will provide guarantee for reducing the dangerous degree, when accidents happened.
