Abstract:
A methodology is introduced to study the dynamics of fluid interfaces in multiphase flows, emphasizing their break-up and coalescence. The algorithm tracks surfaces, here obtained by isocontouring an interface-describing scalar field (e.g., VOF) from a time series of volumetric snapshots. Physical and geometric information of the surfaces is used to find correspondences in a higher-dimensional space. Events are derived from found correspondences to describe the interactions among isosurfaces of...     »
