Kleikemper, J.-A. (2018)
A comparative study of different mesh types for transport processes near gas bubbles regarding accuracy, stability, and run time.
Technische Universität
Bachelorarbeit, Erstveröffentlichung
Kurzbeschreibung (Abstract)
Mass transfer at a single gas bubble rising in incompressible liquid is studied. Only the liquid phase is simulated. A fixed bubble model is used and non-deformable spheroidal gas bubbles with aspect ratio χ = 3 are considered. The Reynolds number is varied between 50 and 500 and two Schmidt numbers, 10 and 100 , are taken into account. Four meshing strategies are compared with respect to accuracy, stability and run-time. The main focus is on mesh sensitivity of the target quantities close to the interface and in the bubble wake. The results are compiled in a Best Practice Guide.
