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 ... -
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 ... -
Modelling of fluid dynamics, mass transfer and chemical reaction in bubbly flows
Rzehak, Roland; Krauss, Manuel (SINTEF Proceedings;2, Chapter; Peer reviewed, 2017)Mass transfer from gas bubbles to the surrounding liquid or vice versa is an important consideration in chemical engineering. Frequently such absorption or desorption processes are accompanied by a chemical reaction in the ...
