Abstract

Multiphase gas-liquid-solid flows are frequently encountered in a variety of industrial processes for the production of synthetic fuels and base chemicals. Examples of relevant process equipment include Slurry Bubble Columns (SBC) and Trickle Bed Reactors (TBR). Due to the very complex topological changes of the interfaces (gas-liquid and liquid-solid), a correct description of the interaction between the phases is extremely difficult. In this paper a novel simulation approach will be presented for complex multiphase flows accounting for i) all important mutual interactions between the phases ii) complex changes in the topology of the interfaces. In view of its fundamental nature, it is an important complementary tool in developing closure equations for Eulerian and/or Lagrangian approaches, which do not capture in sufficient detail the complex topological changes of the interfaces.
