Abstract

Condensation induced water hammer (CIWH) are caused by contact of steam and subcooled water. Thus, modeling the direct contact condensation is a crucial step towards the simulation of condensation induced water hammer with 1D pressure surge codes. Therefore, also the TÜV NORD SysTec GmbH & Co. KG inhouse pressure surge code DYVRO has been equipped with a new contact condensation model. The validation of DYVRO against an experiment dealing with CIWH is presented in this contribution.

Kurzfassung

Kondensationsschläge werden durch den Kontakt von Dampf und unterkühltem Wasser verursacht. Daher ist die Modellierung der Kontaktkondensation ein elementarer Schritt zur Berechnung von Kondensationsschlägen mit 1D-Druckstoßcodes. Dementsprechend wurde für den Druckstoßcode DYVRO, der bei der TÜV NORD SysTec GmbH & Co. KG entwickelt wird, ein neues Kontaktkondensationsmodell implementiert. Dessen Validierung gegen ein Kondensationsschlagexperiment soll im vorliegenden Beitrag vorgestellt werden.
