Investigation of Gas-Liquid Two-Phase Flow Using Three-Field Two-Fluid Model and Two-Group Interfacial Area Transport Equation in CFD Code
Abstract
Prior work has shown that a two-fluid model with a single set of constitutive relations is required to predict a wide range of two-phase flow conditions. The current work is a step in that direction. The 3-D three-field two-fluid model with a two-group Interfacial Area Transport Equation (IATE) has been selected as the required framework with the Computational Fluid Dynamics (CFD) code ANSYS-CFX. The objectives of this proposed work are the following: select a set of constitutive relations and implement these models into CFX; evaluate these models for a wide range of test conditions; if required, develop better models for the interfacial transfer mechanisms.
