Abstract

This thesis develops a hybrid Eulerian–Lagrangian method for insoluble surfactant dynamics in two-phase flow. The bulk flow is solved by a finite-volume method, the interface is captured with a level-set method, and interfacial surfactant transport is represented by Lagrangian particles carrying surfactant mass. To prevent particle clustering, interfacial particle relaxation and adaptive remeshing procedure are introduced. A theoretical framework is further proposed to analyze the relation between particle relaxation to the consistency error.
