N2 - The assessment of the performance of two Heat Transfer Coefficient (HTC) models, derived from the Surface Renewal Theory (SRT) has been carried out based on a two-step approach. First using measurement data of a quasi-steady state horizontal stratified flow, the LAOKOON experiment performed at the TU Munich, and second by simulating a more complex transient experiment carried out at the PMK-2 facility of the KFKi Atomic Energy Research institute Budapest. Both experiments have been simulated with ANSYS CFX 12.1 together with the added HTC models. The Volume of Fluid (VOF) approach, an interface Tracking Method, was chosen for the simulation of the two phase flow dynamics due to its advantage of explicitly solving the interface geometry; in comparison to a standard two fluid Eulerian model. The coupled system of VOF and SRT based HTC calculation demonstrated its potential to simulate transient two phase flows with heat and mass transfer.
