A REEVALUATION OF THE LIFT FORCE IN EULERIAN MULTIPHASE CFD

摘要

This paper describes the progress achieved towards the development of a new approach for modeling hydrodynamic closures in multiphase computational fluid dynamics (M-CFD), and specifically focuses on the analysis of the lift force implementation, which has proved to be a critical challenge. While existing formulations of the lift force (e.g. Tomiyama et al.) have been extensively applied with mixed success, no rigorous verification and validation on fundamental unit tests had been performed previous to this work. Baseline test cases on the drag force are presented, along with the extensive work on the formulation, implementation, and testing of the lift force. Promising results are shown that have the potential to benefit the advancement of M-CFD towards robust industrial applications.
