Abstract
A Hybrid Heat Transfer Coefficient module has been developed based on two Surface Renewal Theory models using CFD simulations. The validation of the model has been done on a meso-scale computational grid for CFD simulations and on a macro-scale computational grid for System Code analysis. The CFD simulation was performed for a stratified co-current two phase flow between saturated steam and sub-cooled water while the System Code analysis was performed for a Condensation Induced Water Hammer experiment.
Kurzfassung
Die Entwicklung eines Hybrid-Moduls zur Berechnung des Wärmeübergangskoeffizienten, basierend auf zwei Oberflächenerneuerungsmodellen, wird vorgestellt. Der Validierungsvorgang umfasst einen Vergleich der Ergebnisse auf zwei verschiedenen Rechengitterskalen; einer Meso- und einer Makroskala, im Falle der CFD Rechnungen bzw. des Systemcodes. Die CFD Untersuchung wurde für eine stationäre, im Gleichstrom fließende Zweiphasenströmung zwischen Sattdampf und unterkühltem Wasser durchgeführt und mit lokalen Messwerten verglichen. Die Nachrechnung mit dem Systemcode bezieht sich auf ein Experiment mit Kondensationsschlägen und wurde mit dessen Messdaten verglichen.
