Title: “Fluid mechanics past hydraulic structures: A shift in paradigm


Traditionally, flows past hydraulic structures have been addressed from the design point of view. More specifically, the concern has been chiefly to provide heights of walls, widths of channels, etc., without much regard to the internal features of the flow. Design formulas have been experimentally obtained for the inception point of air entertainment, for instance, and they have helped develop the hydraulic profession. Very recently, on the other hand, high-fidelity numerical simulations have opened a new avenue, which consists in addressing the turbulent coherent structures leading to the interpretation of flows past hydraulic structures. These simulations are shedding light on the flow features which explain air entertainment, describe eddies upstream and downstream gates, for example, and offer new ways of “seeing” the hydraulic structures. In this presentation, diverse solutions will be discussed, indicating how they compare with past and new observations, including field data, and how they can be used to finally improve the design of those structures. 

About the Speaker

Dr. Fabián A. Bombardelli holds the Gerald T. and Lillian P. Orlob Endowed Professorship in Water Resources, at the Department of Civil and Environmental Engineering of the University of California, Davis (UC Davis). Dr. Bombardelli is a leader in the development of new theoretical and numerical models for multi-phase flows, as well as in their observation in the laboratory and the field. He currently serves as the Editor in Chief of the Journal of Hydraulic Engineering, of the American Society of Civil Engineers (ASCE), and of RIBAGUA, the International Journal of Water of Iberoamerica, IAHR. Dr. Bombardelli received a degree in Hydraulic Engineering from the National University of La Plata, Argentina; a Master degree in “Numerical Simulation and Control” by the University of Buenos Aires, also in Argentina; and a PhD by the University of Illinois, Urbana-Champaign, United States, under the supervision of Prof. Marcelo Garcia. Prior to his move to the States, he was a Researcher in Numerical Models at the National Water Institute for seven years. Since 2004, Dr. Bombardelli is a Professor (now Full with tenure) at the UC Davis.

Dr. Bombardelli is widely known for his research on bubble plumes, sediment transport in open channels, the Basset force, flow in stepped spillways, and for the application of the phenomenological theory of turbulence to hydraulics; in addition, he has developed applied research on water bodies in California. He has published in major research journals of physics, hydraulic engineering and water resources. He has more than 70 publications in these journals and more than140 articles in total. Dr. Bombardelli is a member of the Editorial Board of the Journal Environmental Fluid Mechanics since 2011; Associate Editor of the Journal of Hydro-environment and Research, since 2018; and member of the Review Committee of the Int. Journal of Sediment Research. He has received numerous recognitions such as the Best Reviewer Award of the IAHR (2011), Outstanding Reviewer of the ASCE (2011), the Awards as Outstanding Advisor in Civil Engineering (ASCE, 2015), and Outstanding Advisor in Civil Engineering of the State of California (2015), the Young Alumni Award of the University of Illinois in 2015, Featured Article in Physics of Fluids (2018), EWRI Fellow in 2021, and various awards as a student in Illinois. 12 students have graduated with doctorates and 27 as Master under the supervision of Prof. Bombardelli. He has also worked as a consultant for the government of Argentina and for the United Nations in Peru, in 2011 and 2013, proposing systems of cascades for the very polluted Matanza-Riachuelo, Buenos Aires. He has delivered seminars and keynote lectures in many universities and conferences worldwide.
