OpenFOAM has several heat transfer solvers such as:

  • buoyantBoussinesqPimpleFoam, buoyantBoussinesqSimpleFoam
  • buoyantPimpleFoam, buoyantSimpleFoam
  • chtMultiRegionFoam, chtMultiRegionSimpleFoam

The cht stands for Conjugate Heat Transfer and this set of solvers is applied for multi-physic problems, for example, heat exchangers where both solid phase and fluids on cold side and hot side are available. However, All these solvers are designed for one phase flow and no solver for our topic is available.

In order to investigate heat transfer on drop impact on a solid plate, a solver is created based on OpenFOAM basic solvers: interFoam and chtMultiRegionFoam. The solver tracks the drop interface using the volume of fluid (VoF) method and the heat transfer between the two-phase flow and solid phase is accomplished similarly to chtMultiRegionFoam. I named the new solver chtInterHeatFoam.

The following demo shows the performance of this solver qualitatively:
