A workflow for the sustainable development of closure models for bubbly flows

Hänsch, S.; Evdokimov, I.; Schlegel, F.; Lucas, D.

Many years of research in developing closure models for polydisperse bubbly flows have produced a plethora of empirical and semi-empirical models.
The continuous development and analysis of such models requires their constant validation with the steadily increasing number of validation cases in
the literature.
In this paper we present a pipeline for the fully-automated analysis of OpenFOAM simulations using the Snakemake workflow management system. The pipeline is applied to an extensive collection of well-established validation cases for bubbly flows and allows the fast and efficient production of large amounts of results that are summarized in well-structured reports. An optional post-processing step introduces a fuzzy-logic controller developed for the detailed analysis of these results by quantifying the agreement of the simulation with the available experimental data. It is demonstrated how such quantification enables the systematic evaluation of new closure models and contributes to a more sustainable model development.
