VoF method in multiphase flows [interFoam]

Tutorial link: YouTube Video

Description: In this tutorial, we will learn how to simulate a volume of fluid model based multiphase problem in OpenFOAM. The solver used here is interFoam and using that we will simulate air bubble rising problem in water column. We will also see, how to plot phase fraction plot using gnuPlot script and how to post-process results in paraview.

Points covered:

  • VoF theory
  • Copy a base case
  • Understand folder structure
  • Initialize phase fraction
  • Define properties of each phase
  • Basic runtime post-processing
  • Visualize in ParaView
