RISStudy 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 ...
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 ...
Numerical Investigation of Focused Waves and Their Interaction With a Vertical Cylinder Using REEF3D
