Zusammenfassung
Transport phenomena in multiphase systems is a problem of increasing importance and interest in engineering. Special cases, like dispersed two-phase flows of dust in air, sedimentation in water, boiling and condensation, solidification in melt, etc., occur in many natural and technological situations. Usually, it`s very hard to describe the problem in details, even with the help of modern computers. Of all methods describing multiphase flow system, local volume averaging techniques, together with phase field methods, provide the best framework to advance the understanding of multiphase flow. Furthermore, appropriate efficient solvers should be utilized in order to successfully model this problem. In this presentation, local volume averaging and phase field methods are briefly introduced, some interesting results, obtained both by Finite Volume method (SIMPLE) and Finite Element method (FEATFLOW) are given and discussed.
