In order to analyze the mechanism and impact factors of bubble curtain for mitigating salt intrusion through sea locks,a three-dimensional numerical model of air curtain against saline wedge is established using the two-fluid model and the convection-diffusion model in the OpenFOAM■.Processes of bubble plumes,salty gravity current and prevention of salt intrusion by bubble screen are numerically simulated,respectively.It is obviously from numerical results that the new model can accurately simulate the process of separation of salt and fresh w...
