Abstract
Single phase natural circulation in a rectangular loop is simulated using the PHOENICS code, a general purpose Computational Fluid Dynamics (CFD) code. The rectangular loop, having different operating power levels, has been modeled with the help of the Multiple Block Fine Grid Embedment (MBFGE) technique. The Co-located Co-variant Method (CCM) is used to simulate this loop in PHOENICS. Extensive experimental and CFD studies have been conducted on single phase natural circulation in a rectangular loop. The paper presents the results of three-dimensional CFD analysis for the prediction of steady state behavior in a rectangular loop and its comparison with experimental data. The results of code prediction and readily available experimental data show good agreement.
Kurzfassung
Der Ein-Phasen-Naturumlauf in einer rechteckigen Schleife wird simuliert mit Hilfe des PHOENICS Codes, einem vielseitigen Code in der numerischen Strömungsmechanik (CFD). Die rechteckige Schleife, die mit verschiedenen Leistungsstufen betrieben werden kann, wurde modelliert mit Hilfe des Multiple Block Fine Grid Embedment (MBFGE) Verfahrens. Die Co-located Co-variant Methode (CCM) wurde zur Simulation dieser Schleife in PHOENICS verwendet. Umfangreiche experimentelle und CFD Untersuchungen wurden durchgeführt zur Simulation des Ein-Phasen-Naturumlaufs in einer rechteckigen Schleife. In der vorliegenden Arbeit wird über die Ergebnisse einer dreidimensionalen CFD Analyse zur Vorhersage des stationären Verhaltens in einer rechteckigen Schleife und dem Vergleich mit experimentellen Daten berichtet. Die Ergebnisse der berechneten Vorhersage und der verfügbaren experimentellen Daten zeigen eine gute Übereinstimmung.
