Abstract
By simplifying the boundary conditions of natural gas in double-skin pipeline, standard k-ε turbulent model and CFD method were applied to analyze the characteristics of leakage diffusion, the leakage of diffusion process was simulated, which pressures were 0.6 MPa, 1.0 MPa and1.6 MPa. Results shows that leakage speed and temperature of outer pipe face increases rapidly and temperature reach maximum at the leakage time of 3s. With increasing distance from leakage inlet, temperature and velocity field raises and loared as shock wave.
