Synopsis

Presentation 1: On the structural aspects of the hydraulic engineering (A. Antonini)

As hydraulic engineers, we tend to mainly focus on the hydrodynamic loadings, often neglecting the structural response. However, a proper design or assessment of the structures interacting with waves require an integral approach, that on one hand properly describes the loading conditions but on the other hand also quantifies the response to these forcing. During the talk this intertwined field will be introduced through the numerical and physical modelling of crownwalls and lighthouses. While later, the inverse technique to infer impulsive wave loadings from real structures dynamic responses will be presented.

Presentation 2: Evolution of Pneumatic Tsunami Simulators – from concept to proven experimental technique and what has come after

Many previous tsunami impact studies have relied upon unrealistic waveforms rather than full-duration tsunami waves, or have used simplified models of nearshore and over-land flows. This presentation will describe the evolution through three generations of pneumatic Tsunami Simulators for physical model tests of realistic tsunami. The pneumatic method, originally developed for tidal modelling in the Fifties, has been modernised to generate extraordinarily long waves in a controlled manner, with accurate reproduction of recorded free-surface tsunami field data. Example results are presented from selected research studies that have validated their performance and then used them to quantify tsunami effects.

Presentation 3: Stinger Keel, a Floating Offshore Wind (FLOW) case study: from physical to numerical modelling

The offshore wind industry has experienced significant growth in re-cent years and continues to expand worldwide. The possibility of mounting wind turbines on floating support opens the potential application in deep water resources. Realization of this potential, however, requires cost-effective floating wind turbine designs that can compete with other energy sources. The design and manufacturing of optimized and cost-effective floating wind turbines requires reliable and adequate design tools that can model the dynamics response of floating platforms correctly. During this talk we will be presenting the combined physical and numerical modelling study performed for a floating foundation concept design named Stinge Keel with the goal of assessing its dynamical response and wave loading.

 

About the speakers

Alessandro Antonini is an Assistant Professor of Coastal Structure at Delft University of Technology, the Netherlands. In 2014 he received a Ph.D. in civil engineering from the University of Bologna, while later he worked at the University of Plymouth as a lecturer in Coastal Engineering. Since December 2018 he is Assistant Professor of Coastal structures at TUDelft. His research interests are mostly devoted to the multidisciplinary wave-structure interaction field for the design of marine structures either to protect our coastline or for the harnessing of marine renewable energy.

Ian Chandler is a Senior Engineer within HR Wallingford’s Engineering Group. He has over 10 years’ experience of physical and computational modelling of hydraulic and coastal structures. Ian has particular experience in physical modelling overtopping and of tsunami propagation and interaction with coastal defences and buildings. Previous to joining HR Wallingford Ian completed a PhD at the University of Warwick studying the mixing of solute pollutants across the sediment-water interface, specifically the vertical variation in mixing coefficient.

George Pouliasis is an Engineer within HR Wallingford’s Coasts and Oceans Group. His primary work concerns the simulation of offshore and nearshore wave processes for the design and impact of coastal structures. George has a particular interest in the numerical modelling of nearshore processes (e.g. wave breaking) and wave-structure interaction. Before joining HR Wallingford, he has worked within the Water Resources sector as a numerical modeller. He holds a Civil Engineering Diploma from the National Technical University of Athens and is currently pursuing his MSc in Hydraulic Engineering at the Delft University of Technology, partially funded by scholarship.
