Numerical Analysis for Two Dimensional Gas-liquid Two-phase Flows with Obstacles

摘要

A numerical analysis for gas-liquid two-phase flows with obstacles has been performed using modified drift-flux model. A validity of the model for an application to a multi dimensional multi-phase flows was verified in the previous report. The basic equations and boundary conditions in the analysis are described first. An effect of the obstacles on the flows is represented as the term of general pressure loss in the momentum equation.
