Multiscale Methods for the Reliable Simulation of Multiphase Processes

Abstract

Multiphase problems are ubiquitous in science and engineering. In all cases these problems are characterized by interfaces that evolve, thus any simulation procedure developed to address them must be able to effectively track the interfaces. In cases where the key interface physics is limited to the motion of the interface between phases (e.g., breaking waves, hydraulic jumps, plunging jets, etc.) modeling methods that employ an implicit representation of the phase interfaces have been successfully developed. These methods are popular because they avoid the geometric complications of explicitly tracking interfaces.
