A Computational Fluid Dynamics Approach for Modeling the Fluid–Structure Interaction of Offshore Aquaculture Cages and Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Open ocean aquaculture cages became a promising alternative to traditional fish cage designs recently. The offshore environment implies larger loads on the structure and thus higher risk for fish loss. Floating rigid ...
An Improved Direct Forcing Immersed Boundary Method With Integrated Mooring Algorithm for Floating Offshore Wind Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An upgraded direct forcing immersed boundary method is implemented in the open-source hydrodynamic framework REEF3D::CFD for simulating the six-degrees-of-freedom motions of a floating offshore wind turbine (FOWT) based ...
Study of Water Impact and Entry of a Free Falling Wedge Using Computational Fluid Dynamics Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many offshore constructions and operations involve water impact problems such as water slamming onto a structure or free fall of objects with subsequent water entry and emergence. Wave slamming on semisubmersibles, vertical ...
REEF3D::FNPF—A Flexible Fully Nonlinear Potential Flow Solver
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In situations where the calculation of ocean wave propagation and impact on structures are required, fast numerical solvers are desired in order to find relevant wave events. Computational fluid dynamics (CFD)-based numerical ...
Numerical Simulation and Analysis of Phase-Focused Breaking and Non-Breaking Wave Impact on a Fixed Offshore Platform Deck
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Extreme wave impact due to tsunamis and storm surge create large wave heights that cause destruction to coastal and offshore structures. Focused waves have been used to represent such extreme waves, and in the present ...
A Numerical Study of the Hydrodynamics of an Offshore Fish Farm Using REEF3D
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, the hydrodynamics of and nonlinear interaction between the large offshore fish farm “ShenLan 1” and regular waves are investigated using the open-source computational fluid dynamics (CFD) toolbox REEF3D. ...
Computational Fluid Dynamics Investigations of Breaking Focused Wave-Induced Loads on a Monopile and the Effect of Breaker Location
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of new offshore structures requires the calculation of the wave-induced loads. In this regard, the computational fluid dynamics (CFD) methodology has shown to be a reliable tool, in the case of breaking waves ...
Identification and Investigation of Extreme Events Using an Arbitrary Lagrangian–Eulerian Approach With a Laplace Equation Solver and Coupling to a Navier–Stokes Solver
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Increased deployment of offshore wind turbines is seen as an important pathway to increase green renewable energy production. Improved and rapid identification of extreme events and evaluation of hydrodynamic loads due to ...
REEF3D Wave Generation Interface for Commercial Computational Fluid Dynamics Codes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, computational fluid dynamics (CFD) developments have shown a trend to combine Reynolds-averaged Navier–Stokes (RANS) CFD simulation with other methods such as wave theories or velocity potential-based ...
Three Dimensional Numerical Modeling of Pier Scour Under Current and Waves Using Level Set Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A threedimensional (3D) computational fluid dynamics (CFD) model is used to calculate the scour and the deposition pattern around a pier for two different boundary conditions: constant discharge and regular waves. The CFD ...
