A Baseline model for monodisperse bubbly flows
Rzehak, Roland; Krepper, Eckhard; Ziegenhein, Thomas; Lucas, Dirk (SINTEF Proceedings;1, Chapter, 2015)For practical applications the Euler-Euler two-fluid model relies on suitable closure relations describing interfacial exchange processes. The quest for models with a broad range of applicability allowing predictive ... -
CFD‐simulation of boiling in a heated pipe including flow pattern transitions using a multi‐field concept
Höhne, Thomas; Krepper, Eckhard; Lucas, Dirk (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)The paper presents the extension of the GENTOP model for phase transfer and discusses the sub-models used. Boiling flow inside a wall heated vertical pipe is simulated by a multi-field CFD approach. Sub-cooled water ... -
IMPROVEMENT OF EULER-EULER SIMULATION OF TWO-PHASE FLOW BY PARTICLE-CENTER-AVERAGED METHOD
Lyu, Hongmei; Schlegel, Fabian; Rzehak, Roland; Lucas, Dirk (SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)The standard Euler-Euler modelling is based on the phase-averaged method and the forces of the bubble are the function of gas volume fraction. However, the closure models for the forces are developed based on the measured ...
