Introduction

This tutorial examines the flow of water and air in a tee junction. Initially you will solve the problem using the less computationally intensive mixture model, and then turn to the more accurate Eulerian model. The results of these two approaches can then be compared.

This tutorial demonstrates how to do the following:

• Use the mixture model with slip velocities.

• Set boundary conditions for internal flow.

• Calculate a solution using the pressure-based coupled solver with the mixture model.

• Use the Eulerian model.

• Calculate a solution using the multiphase coupled solver with the Eulerian model.

• Display the results obtained using the two approaches for comparison.
