Summary on Grant Application Form
Velocities and accelerations will be measured under extreme waves combined with currents using PIV and the results compared to high order wave theories. Hydrodynamic forces will also be measured on a model TLP. Velocity patterns will also be measured around the complete TLP model in high waves and currents, and in extreme three dimensional sea states. The dynamic response of TLPs to extreme waves in combination with shear currents will be investigated. Velocity and acceleration distributions under breaking or near breaking waves will be collected. Further tests will be carried out at Edinburgh on breaking waves combined with currents, utilising the particle image velocimetry flow mapping technique and existing velocity data will be further analysed to estimate accelerations. Tests will also be carried out in the towing/wave tank at Glasgow to evaluated hydrodynamic forces, and specifically low and high frequency viscous and wave characteristics of the TLP model in extreme wave and current combinations. Velocities and accelerations measured by experiment will be compared to the high order wave theories of Dean and Chapling, and also to Peregrine's boundary integral time stepping technique. Techniques for adding shear currents will also be examined.
