CHAPTER 104 FORCES ON AND PARTICLE MOTIONS AROUND SUBMERGED STRUCTURES IN STEEP WAVES

Jesper Skourup, Ivar Jonsson

A boundary integral equation method combined with a non-linear time stepping procedure for the free water surface is developed for simulations of the interaction between highly non-linear water waves and fixed submerged horizontal cylinders. The wave forces on the cylinders are computed and a good correspondence is found with other computed results for low Keulegan-Carpenter numbers. A new method for tracing the orbits of water particles in the fluid domain is developed, and the influence from
