Effective momentum induced by steam condensation in the oscillatory bubble regime
Gallego-Marcos, Ignacio; Kudinov, Pavel; Villanueva, Walter; Puustinen, Markku; Räsänen, Antti; Tielinen, Kimmo; Kotro, Eetu (Elsevier, 01.06.2019)The spargers used in Boiling Water Reactors (BWR) discharge steam from the primary coolant system into a pool of water. Direct steam condensation in subcooled water creates sources of heat and momentum determined by the ... -
Pool stratification and mixing induced by steam injection through spargers: analysis of the PPOOLEX and PANDA experiments
Gallego-Marcos, Ignacio; Kudinov, Pavel; Villanueva, Walter; Kapulla, Ralf; Paranjape, Sidhart; Paladino, Domenico; Laine, Jani; Puustinen, Markku; Räsänen, Antti; Pyy, Lauri; Kotro, Eetu (Elsevier, 20.07.2018)Spargers are multi-hole injection pipes used in Boiling Water Reactors (BWR) and Advanced Pressurized (AP) reactors to condense steam in large water pools. A steam injection induces heat, momentum and mass sources that ... -
Pool stratification and mixing induced by steam injection through spargers: CFD modelling of the PPOOLEX and PANDA experiments
Gallego-Marcos, Ignacio; Kudinov, Pavel; Villanueva, Walter; Kapulla, Ralf; Paranjape, Sidharth; Paladino, Domenico; Laine, Jani; Puustinen, Markku; Räsänen, Antti; Pyy, Lauri; Kotro, Eetu (Elsevier, 29.03.2019)Spargers are multi-hole injection pipes used in Boiling Water Reactors (BWR) and Generation III/III+ Pressurized Water Reactors (PWR) to condense steam in large water pools. During the steam injection, high pool surface ...
