报告题目:FloatStepper - a robust algorithm for floating body simulations
报告摘要:
In this talk we present the so-called added mass instability, which a common numerical problem encountered in floating body simulations when the floating body is lighter than the surrounding fluid. We demonstrate how the instability can occur in simulation using the open-source software package OpenFOAM, and show how our newly invented algorithm, FloatStepper, can remove this problem by explicitly calculating the added mass force on the floater.
主讲人简介:
Johan Roenby got his PhD degree of theoretical hydrodynamics at Denmark Technology University in 2011. From 2011 to 2017, he served as a research scientist, DFF-Research Talent Postdoc, and CFD team leader of Ports & Offshore Technology (POT), Denmark Hydrodynamics institution (DHI). In 2017, he found his company STORMING. The business scope is mainly on the R&D, consultancy and training within fluid simulation technology. He also serves as the associate professor in mathematics at Roskilde University, Denmark, and specialises in numerical methods for fluid dynamics simulations. He develops several mathematical models and numerical algorithms which are implemented mainly in the open source CFD toolbox, OpenFOAM.

报告题目:Physical testing with scaled models of ORE technology
报告摘要:
For advancing Offshore Renewable Energy (ORE) technology— wave, tidal, and offshore wind and solar systems. Scaled models, designed to replicate energy captor physics at full scale prototypes under controlled laboratory conditions (e.g., wave tanks, wave basins, and wind tunnels), address critical limitations of numerical simulations by capturing real-world nonlinearities (e.g., wave-structure interaction, turbulent flow). Key testing objectives include validating performance metrics (e.g., energy capture efficiency, load resistance), optimizing design parameters (e.g., device shape, mooring systems), and assessing resilience to extreme offshore environments (e.g., storm surges, high winds). Results from scaled-model testing provide valuable data to validate and refine numerical models, reduce full-scale deployment risks, and accelerate the commercialization of cost-effective, reliable ORE technologies.
主讲人简介:
Efrain Carpintero Moreno completed his PhD at the University of Manchester in 2015, focused on the development of Offshore Renewable Energy (ORE) conversion systems. After completing his PhD, He became a research associate at the University of Manchester. In July 2020, he began his tenure at Ghent University as a researcher and scientific consultant for the Blue Accelerator project. In addition to his academic and research activities, he serves as chair of the IEC – TC114 Marine Energy – Wave, Tidal and Other Water Current Converters committee within the Belgian Electrotechnical Committee, where he contributes to developing and applying high-quality protocols and standards for the marine sector.

报告题目:Hydrodynamic analysis on scour around scaled piles of nearshore wind energy farms in a broken wave region – field investigations
报告摘要:
This presentation shows the results of a numerical investigation on the near-bed flow patterns and scour around the head of OWC wave energy caisson, using linear waves. To predict scour depth around the OWC wave energy structure, Hydrodynamic module (HD) and Sediment Transport (ST) module of MIKE21 have been used under different wave and current conditions. The Keulegan-Carpenter number (KC), based on the width of the OWC is found to be the major parameter that governs the flow and the equilibrium scour depth. Basic flow parameters are studied as function of KC. The scour depth is found to increase with increasing the Keulegan-Carpenter number. This study gives an insight on the potential design perspectives of OWC foundation structure seen as a gravity structure. An array of OWC can be used as replacement of breakwaters, which would be more efficient and serve multipurpose.
