HZDR baseline model for poly-disperse bubbly flows
The baseline model was developed for bubbly flow with bubble sizes larger 1 mm and validated for many cases.
Depending on the expected bubble size distribution a decision has to be done whether a mono-disperse approach is sufficient or a polydisperse approach (iMUSIG) has to be used. The definition of the closure models and constants used in the present baseline model version can be downloaded here.
