The Sustainable Development of CFD Models for Bubbly Flows with a Snakemake Workflow and Fuzzy Logic

Many decades of developing closure models for bubbly flows have produced a vast amount of available models and validation cases. There is still no consensus in the multiphase community about the use of those closure models and little progress is seen towards Eulerian-Eulerian simulations with reliable predictive abilities. The accumulation of model options and validation data makes it increasingly difficult to give best practice guidelines for the simulation of bubbly flows.

However, the huge amount of data allows us to explore the opportunities arising with the use of fast and efficient workflows and data science tools.

This talk presents the baseline model strategy developed at the CFD department, and its current realization using a Snakemake workflow for the fully-automated processing of OpenFOAM cases. For the evaluation of results a fuzzy logic controller is demonstrated. It is designed to compare the performance of new closure models against the current baseline model set with the aim to add to a more sustainable model development in the future.
