ACoolTPS - Advanced Cooling of High Power Microsystems using Two-Phase Flows Systems in Complex Geometries

Abstract

The present work aims at developing a new flexible computational framework based on modern programming language to simulate macro and microscale two-phase flows with dynamic boundaries in complex geometries sponsored by The Royal Society - Advanced Newton Fund. Such a technique is extremely useful for periodic and very large domains which requires exhaustive computational resources, consequently, reducing the required numerical domain. In this presentation the one-fluid interface tracking Finite Element (FE) method is used to solve the equations governing the motion of two immiscible incompressible fluids in the Arbitrary Lagrangian-Eulerian framework (ALE). The equations are written in axisymmetric coordinates; however, the proposed moving boundary technique can be extended to 3-dimensional flows and any other methods using the ALE framework such as the finite volume method.
