Abstract [en]

Within the course of the master thesis project, two thermal phase change models for direct contact conden-sation were developed with different modeling approaches, namely inter-facial heat transfer and combustionanalysis approach.

After understanding the OpenFOAM framework for two phase flow solvers with phase change capabilities, a new solver, including the two developed models for phase change, was implemented under the name of interPhaseChangeCondenseTempFoam and analyzed in a series of 18 tests in order to determine the physical behavior and robustness of the developed models. The solvers use a volume-of-fluid (VOF) approach withmixed fluid properties.

It has been shown that the approach with inter-facial heat transfer shows physical behavior, a strong timestep robustness and good grid convergence properties. The solver can be used as a basis for more advanced solvers within the phase change class.
