The present paper shows the influence of considering polydispersity of bubbly flow, simulating bubble columns with a three‐dimensional Eulerian two‐fluid model. A complete set of interfacial closure models regarding drag force, lift force, wall force, turbulent dispersion force and bubble‐induced turbulence is considered. A round bubble column of 0.288 m diameter and 2.5 m height is simulated up to...
Gewebestrukturen werden oft zur Separation von Feststoffpartikeln eingesetzt. Bei der Gewebedurchströmung erfolgt die Phasentrennung durch Filtration. Die Kenntnis über den Charakter der Strömung kann gewinnbringend zur Optimierung dieser Filtrationsstrukturen bzw. zur Reduzierung des Druckverlustes und zur Vorhersage des Trennkorns eingesetzt werden. Eine CFD‐Simulation ermöglicht die Berechnung...
