Advances in Computational Modeling of Wave Structure Interaction Problems

Dear Colleagues,

Development of accurate and efficient tools for modelling wave structure interaction problems is fundamental to many offshore and ocean engineering applications.  Over the last few decades, with the constant advances in computer technology and numerical techniques, computational fluid dynamics (CFD), in the form of a numerical wave tank (NWT), has increasingly been adopted and become an integral part in the design and testing of new offshore and marine structures. Many commercial, in-house, and open source CFD codes have been developed and can be applied to model the complex wave structure interaction flow problems. However, to apply these models in real engineering design, a number of challenges remain.  For example, the computational costs of these models, even run on high-performance computers (HPCs), are still far too high, so an approach based on coupling flow solvers of varying fidelity, e.g., a potential flow-based solver and a multiphase Navier–Stokes solver will be essential. For problems involving multiple physics and temporal/spatial scales, new techniques need to be developed for effective and efficient model integration, as well as implementation on HPCs. 

The aim of this Special Issue is to disseminate the latest advancement in CFD techniques for emerging offshore and ocean engineering applications. A key focus will be on the development of efficient multi-physics and multi-scale models which can be used to aid the design and deployment of the next generation offshore engineering structures, including offshore renewable energy converters. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Development of techniques for effective and efficient coupling of multi-physics/multi-scale models;
• Modelling of extreme loading on offshore renewable energy converters (wave, wind and tidal);
• Physical model tests for validating CFD tools;
• Modelling the coupled wind, wave and current loads on offshore structures;
• Integrated numerical wave tank for modelling wave structure interaction including hydro-elasticity effects and mooring line dynamics;
• Sloshing flow:  applications and mitigation;
• Code integration through coupling libraries, such as PreCICE and MUI;
• Parallel implementation on traditional and emerging HPC architectures;
• Applications of artificial intelligence and machine learning in CFD for improved model efficiency and accuracy. 

We look forward to receiving your contributions.
