Special Issue Information

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.

We report on the development and validation of a 3D hybrid Lattice Boltzmann Model (LBM), with Large Eddy Simulation (LES), to simulate the interactions of incompressible turbulent flows with ocean structures. The LBM is based on a perturbation method, in which the velocity and pressure are expressed as the sum of an inviscid flow and a viscous perturbation. The far- to near-field flow is assumed to be inviscid and represented by potential flow theory, which can be efficiently modeled with a Boundary Element Method (BEM). The near-field perturbation flow around structures is modeled by the Navier–Stokes (NS) equations, based on a Lattice Boltzmann Method (LBM) with a Large Eddy Simulation (LES) of the turbulence. In the paper, we present the hybrid model formulation, in which a modified LBM collision operator is introduced to simulate the viscous perturbation flow, resulting in a novel perturbation LBM (pLBM) approach. The pLBM is then extended for the simulation of turbulence using the LES and a wall model to represent the viscous/turbulent sub-layer near solid boundaries. The hybrid model is first validated by simulating turbulent flows over a flat plate, for moderate to large Reynolds number values, Re ∈[3.7×104;1.2×106]; the plate friction coefficient and near-field turbulence properties computed with the model are found to agree well with both experiments and direct NS simulations. We then simulate the flow past a NACA-0012 foil using a regular LBM-LES and the new hybrid pLBM-LES models with the wall model, for Re = 1.44×106. A good agreement is found for the computed lift and drag forces, and pressure distribution on the foil, with experiments and results of other numerical methods. Results obtained with the pLBM model are either nearly identical or slightly improved, relative to those of the standard LBM, but are obtained in a significantly smaller computational domain and hence at a much reduced computational cost, thus demonstrating the benefits of the new hybrid approach.

Investigating the wave hydrodynamics of free-surface flow over rippled bottoms is a continuing concern due to the existence of submarine multiple sandbars and ambient flow in coastal and estuarial areas. More attention to free-surface wave stimulation has been received from the perspective of resonant wave-wave interaction, which is an intensive way for wave energy transfer and a potential way for wave component generation. However, the basic behavior of the triad resonant interaction of this problem is still limited and unclear. In this study, the triad resonant interaction induced by steady free-surface flow over rippled bottoms is numerically investigated by means of the High-Order Spectral (HOS) method. By considering the interactions among free-surface waves, ambient current, and rippled bottoms, the numerical model is applied for this situation based on Zakharov equation with ambient flow term. The temporal evolution of the triad resonant wave amplitude has been numerically investigated and compared well with multiple-scale expansion perturbation theory. Specifically, the temporal evolution behaviors of all six triad resonant wave components are confirmed by both numerical simulation and nonlinear perturbation analysis. Full article
