OpenFOAM has two solvers (chtMultiRegionFoam and chtMultiRegionSimpleFoam )  for the simulation of heat transfer across different materials.  When a solver has the keyword simple in its name in OpenFOAM, it means it uses SIMPLE algorithm for pressure-velocity decoupling, Moreover, it represents it is a 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 solvers are developed in OpenFOAM such as:

  • olaFoam (or olaFlow)
  • wave2Foam

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

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