Numerical analysis of a lock-release oil slick

A multiphase MPS solver for modeling multi-fluid interaction with free surface and its application in oil spill

“…When the large-scale oil spills are simulated, the turbulence effect should be considered [15,16,50,51]. The present study is developed in the large eddy simulation (LES) framework with consideration of the sub-particle-stress (SPS) turbulence model [57,58].…”

“…(12) and (13) are satisfied, the conditions of Eqs. (14) and (15) will be invoked to test further; otherwise, the particle is regarded as an internal liquid particle. distance from the nearest A-type particle is smaller than ×l 0 , where =2.1…”

“…Namely, the oil spilling problem was simplified as a two-phase flow by assuming free surface as a "free-slip rigid-cover" (i.e. neglecting free surface deformation) [15,16]. For example, Zeng et al [15] adopted this assumption and utilized a turbulent two-phase VOF method to simulate oil slick spreading.…”

“…neglecting free surface deformation) [15,16]. For example, Zeng et al [15] adopted this assumption and utilized a turbulent two-phase VOF method to simulate oil slick spreading. Gong et al [16] utilized a similar method (coupling the k- turbulence model with two-phase VOF in OpenFOAM) to simulate the leaking behaviors of oil slicks behind containment booms.…”

“…Gong et al [16] utilized a similar method (coupling the k- turbulence model with two-phase VOF in OpenFOAM) to simulate the leaking behaviors of oil slicks behind containment booms. However, the effects of wave or continuous spilling cannot be analyzed by these methods [15,16] owing to the neglect of free surface deformation in the "rigid-cover" assumption.…”
