A new non-overlapping concept to improve the Hybrid Particle Level Set method in multi-phase fluid flows
A novel non-overlapping concept is augmented to the Hybrid Particle Level Set (HPLS) method to improve its accuracy and suitability for the modelling of multi-phase fluid flows. We first diagnose the key flaws in existing particle level set methods, that may result in the misplacement of newly seeded particles in the opposite signed domain. The non-overlapping concept effectively prevents the misplacement of particles during reseeding operations and thereby relaxes the common restriction placed on escaped particles. The concept is examined with a number of challenging test cases, including both the level-set-only simulations and the two-phase fluid flows.
