    • 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 ...
