Numerical Simulation and Influencing Factors Analysis of the Leakage and infiltration diffusion for Fuel Underground Storage Tank

Abstract:

Mass and heat transfer processes of three fuels commonly used (Liquefied Petroleum Gas (LPG), gasoline, diesel oil) flow dispersing in underground environment for the leak at different zones of underground storage tank (UST) were studied. On the basis of the mass and heat transfer process analysis and employing the three-dimensional multiphase mixture flow model, the migration processes of LPG, gasoline, diesel oil in tank pond for UST leak were simulated. The velocity, density, concentration, pressure, temperature fields can be obtained. From the simulation results, the detailed analysis were performed to investigate the characteristics of the three fuels infiltration flow processes and the effects of various influencing factors on infiltration flow such as storage pressure, fuel composition, leak position of tank, position of outlet, gravity, viscous force, etc.
