Simulation on Leakage and Proliferation Model of High-pressure Long-distance Natural Gases Pipeline Based on Matiab

The rupture of high-pressure natural-gas pipeline would threaten people and property around. To estimate the mass flow rate of the accidental leakage is very important to hazard analysis and/or risk management for high-pressure and long-distance natural gas pipeline supply system. The establishment of a proliferation of gas pipeline leakage model is one of key technologies to assess the loss of gas pipeline accident. The design focuses on natural gas leakage and the proliferation mechanism of the process, and uses Gaussian Plume, smoke specific research model to calculate the leak speed, flow leakage, and leakage of pressure gas pipeline. Furthermore, the calculation model for displacement vector in three-dimensional space was gained. The concentration of natural gas leakage coverage areas and the range of the polluted area were investigated.
