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 problem, for example heat exchangers where both solid phase and fluids in 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 solid plate, a solver is created based on OpenFOAM basic solvers: interFoam an chtMultiRegionFoam. The solver tracks the drop interface using volume of fluid (VoF) method and the heat transfer between two phase flow and solid phase is accomplished similar to chtMultiRegionFoam. I named new solver chtInterHeatFoam.
The following pictures, show the performance of this solver:
