OpenFOAM has two solvers (chtMultiRegionFoam and chtMultiRegionSimpleFoam )  for simulation of heat transfer across different materials.  When a solver has the keyword simple in it’s name in OpenFOAM, it means it uses SIMPLE algorithm for pressure-velocity decouple, Moreover, it represent it is an steady solver.

The major two phase flow regime in the micro tubes is the Slug flow regime. In this case there is one or few bubbles inside the channel. Hence, it is usually using surface tracking techniques for simulation of two-phase flow in micro tubes.

For numerical simulation of wave body interaction several solver is developed in OpenFOAM such as:

  • olaFoam (or olaFlow)
  • waveFoam

Those solvers are developed based on OpenFOAM solver interFoam which is a VoF solver. In this post, i will discuss about olaFoam

Vortex shedding is a common phenomena when a fluid flow passes  around a body. Here, the vortex shedding of viscoelastic fluid around oscillating cylinder is simulated.  For simulation, dynamic mesh library is added to OpenFOAM solver viscoelasticFluidFlow. The solver is available only in foam-extended versions.
