Abstract
A rogue wave is a huge wave that is generated by wave energy focusing. Rogue waves can cause critical damage to ships and offshore platforms due to their great wave energy and unpredictability. In this paper, to generate a rogue wave, a bull’s-eye wave, which is a focusing of multi-directional waves, was simulated in a numerical wave tank. A multi-directional wave generating boundary was developed using OpenFOAM, which is an open-source computational fluid dynamics (CFD) library. The wave height and profile of the generated rogue wave were compared to those of the regular wave. In addition, the pressure and velocity contours of water particles and velocity vectors at the free surface of the rogue wave were studied, along with the kinematic and dynamic effects of the rogue wave on a floating body.
Highlights
The physical mechanism of the rogue wave can be explained by wave-current interaction, wave-wind interaction, geometrical seabed variation, and spatial-temporal focusing
A rogue wave was measured at the Draupner platform in the North Sea [1]
The velocity-pressure coupling, and overall solution procedure were based on the PIMPLE algorithm, which combines the semi-implicit method for pressure linked equation (SIMPLE) algorithm and the pressure-implicit with splitting of operators (PISO) algorithm
Summary
A rogue wave, called a freak wave, refers to a wave more than twice the surrounding significant wave height. The physical mechanism of the rogue wave can be explained by wave-current interaction, wave-wind interaction, geometrical seabed variation, and spatial-temporal focusing. The great wave height and unpredictability of a rogue wave mean that it can cause significant damage to ships and offshore platforms. A rogue wave was measured at the Draupner platform in the North Sea [1]. Its significant wave height was 11.9 m, the measured crest height was 18.5 m, and the measured trough height was −7.5 m. The wave height of the rogue wave was 26 m, and it was asymmetric about the still water level. The asymmetry rogue wave’s crest height was extreme and unpredictable [1]
