Viscous numerical wave tank for Bragg resonance by cnoidal and Stokes waves

In this study, a quadtree-adaptive viscous numerical wave tank in which the free surface is resolved by the volume of fluid method is established to solve Bragg resonance caused by Stokes and cnoidal waves. Numerical wavemakers of third-order cnoidal and fifth-order Stokes waves are implemented. Additionally, a numerical damping zone is implemented such that the numerical grid in that area is automatically coarsened under a prescribed low resolution in which the time-matching is more efficient without an excessively small time-step.

ANN for Forecasting Wave Heights along a Ship’s Route during Hurricanes

Congratulate to Prof. Wei. Our paper of Journal of Waterway, Port, Coastal, and Ocean Engineering is online. A data-driven prediction model using numerical solutions is proposed for forecasting wave heights along shipping routes during hurricanes. The developed model can be used to determine the wave heights on a ship’s trajectory, considering a short time step of a ship’s operation.
