Experiments, modeling, and numerical work are being conducted organically with the goal of enabling a two-phase flow CFD-based reactor design. This presentation will give an overview of one of the action items of this project, the numerical analysis of the void fraction distribution in flow boiling using the two-phase flow CFD.
