# Multiphase modeling

Multiphase modeling is a challenging task. With these tutorials you will learn, how to model flows, where you have multiple phases.

# Multiphase modeling

**Intro and Overview**

**Different models for multiphase flows**- Hoste and Jasak provide a in-depth introduction into a variety of models for multiphase flows.

**Volume of Fluid**

**Volume-of-fluid method - dam break case**- Nagy provides a walk through of the dam break tutorial. ***Multiphase**- Use the interFoam solver to simulate breaking of a dam for 2s.**Volume-of-fluid method - two examples**- Guerrero details on setup, control and monitor of VoF simulations.**Multiphase (VOF) simulation project**- In this video series Nagy guides you through an entire simulation project for a multiphase (VOF) flow from the geometry over mesh set up and creation as well as case set up and running the simulation up until the evaluation of the results.**Hysing benchmark**- In this tutorial you will find a reference test case for VoF simulations. It is an elementary quantitative benchmark configuration with reference data in literature.**Bubble rising in a spiralling path in a large tank**- In this tutorial you will learn about a spralling buble rising.**How to use free-surface flows in OpenFOAM**- Here you will find a compact introduction to the theory behind free surface flows in OpenFOAM, a step-by-step guide to run the 2D spillway tutorial and an intro for hydrodynamic instabilities (simulation of Rayleigh - Taylor instability).**The stationary droplet**- In this tutorial you will learn about how to reduce the spurious currents appearing in VoF simulations.
