ERCOFTAC Summer School ”Fluids under Control” organised by Tomas Bodnar, PC Czech Republic,
took place on the 23rd - 27th August 2021
at Department of Technical Mathematics, Faculty of Mechanical Engineering,
Czech Technical University in Prague, Czech Republic.

The summer school was organized as a multidisciplinary event with topics ranging from theoretical and numerical mathematics up to physics and applications. As the title Fluids under Control indicates, all presentations and mini courses had something to do with control problems in fluid mechanics, either from the mathematical or physical point of view.

The applications and numerical methods for solving the corresponding models were also discussed in detail. The emphasize was on models related to topics originating in environmental, biomedical and industrial applications. The summer course was prepared for graduate students, young scientists, and other interested specialists. Besides of the course lectures, the program included a workshop dedicated to short, more advanced lectures given either by attending senior scientists or by the invited summer school students.

Despite of the very complicated conditions and the hybrid regime of the event the summer school was very successful. We have received monograph based on the course lectures. Another book is prepared collecting the selected contributions from the workshop. It’s our intention to continue in this series of summer schools named Prague-Sum in the future.
