Simulation study on oil containment boom based on SPH method
A numerical model for solid-liquid coupling and two-phase flow is developed based on the smoothed particle hydrodynamics(SPH)method to address issues such as flow-solid coupling,instability in two-phase flow of water and oil,poor computational efficiency,and the assumption of a slip wall with no consideration of oil barrier movement in traditional computational fluid dynamics(CFD)methods for simulating oil spill containment using oil booms.Five different skirt structures of oil booms are incorporated into the numerical simulation model of two-phase liquid interaction.By setting relevant parameters in the SPH code,the computational efficiency is improved,and accurate values for the length of oil retention by the oil boom and the oil spill failure step were obtained.The results show that the effectiveness of oil spill containment by the oil boom depends on the ratio of upper and lower skirt heights and the type of skirt angle.A higher ratio of upper skirt height leads to better oil retention performance.The oil boom with a forward folding skirt angle performs better than the one with a forward turning skirt angle.The length of oil retention is influenced by the properties of the oil;smaller density and viscosity of the oil result in a greater length of oil retention.
