Welcome to Day 9. Today we will start tackling another big topic in CFD, multiphase modelling. It is important to understand the idea behind the models and how to include them into your simulation. For this reason we will take a look at the available models and take a detailed look at the VOF model and run several simulations to gain experience.
Go back to "3 weeks" series.

Multiphase modelling (VOF)
In this tutorial you will get a compact introduction on the theory of the Volume-Of-Fluid (VOF) model and it application. You will understand, which additional entries you require in your simulation setup in order to correctly depict the additional physics in the problem. The pdf version can be found here. The focus is on:
- modelling of two immiscible fluids
- case setup
- initial and boundary conditions
- grid refinement
- post-processing
Multiphase modelling (VOF) - flushing a tank
In this next tutorial you will further deepen your knowledge of the theory and gain experience by running further simulations.
Multiphase, free surface flows and rising bubbles
These videos let all the gained information sink in. With it you will be able to understand the simulations you ran up until now and you will implement this knowledge in upcoming cases. You will learn about
- multiphase flow modelling
- Eulerian multiphase model
- free surface flow modelling
- free surface tracking
- Lagrangian particle tracking
- liquid film model
Free surface flows
In this tutorial you will be guided through another application of free surface flows in order to fully internalize the gained knowledge and experience. The focus is on
- theory
- mesh creation
- physical properties
- boundary conditions
- fields initialization
- numerics
End of Day 9
We hope, that you enjoyed Day 9. We hope, that you had fun. You learned a lot about multiphase modelling and especially the Volume-Of-Fluid Method. Tomorrow we will carry on with parallelization. See you tomorrow!
If you've finished the day with time to spare, why not try the additional examples below!
