Abstract
In this work a mixed Eulerian-Lagrangian algorithm, called ELAFINT (Eulerian Lagrangian Algorithm For INterface Tracking) is further developed and applied to compute flows with solid-fluid and fluid-fluid interfaces. The method is capable of handling fluid flows in the presence of both irregularly shaped solid boundaries and moving boundaries on a fixed Cartesian grid. The field equations are solved on an underlying fixed grid using a collocated variable, pressure-based method. The moving boundary is tracked explicitly by the Lagrangian translation of marker particles. The moving boundary passes through the grid and the Immersed Boundary Technique is used to handle the interaction of such a boundary with the underlying grid. The internal solid boundaries are dealt with by using a cut-cell technique. Particular attention is directed toward conservation and consistency in the vicinity of both the solid-liquid as well as fluid-fluid boundaries. The complex geometry feature has been tested for a range of Reynolds numbers. The performance of the immersed boundary implementation is demonstrated for deformation of viscous Newtonian drops. The capabilities developed here can be beneficial in solving a variety of flow problems involving moving and stationary complex boundaries.
