Ship Dynamics in the Surf Zone Model Testing
2008
Quintero, Miguel | Schaffer, Faydra
The aim of this project was to generate data to identify the forces and motions on a ship model while positioned in breaking surf. The two types of breaking waves analyzed were plunging and spilling waves. A 140 feet long model test basin at the Naval Surface Warfare Center Carderock Division (NSWCCD) was used to create the waves with a flap wave maker and the heave motions, pitch motions, and surge forces found acting on the model were measured. To create a breaking wave, a beach was built to represent an actual beach slope and continental shelf slope. The ship model tested is similar to landing craft that operate in the surf zone: broad beam and shallow draft. All data will be utilized in a Master's thesis where it will be thoroughly analyzed and used to create a transfer function that will help predict ship motions and forces in actual seaways.
