1. Mooring dynamics for wave energy applications
Sammanfattning : This work aims to increase the modelling accuracy of two important problems for the wave energy industry. One concerns the mooring dynamics in the presence of snap loads (shock waves in cable tension). The other is related to nonlinear effects in the resonance region of moored wave energy converters (WECs). LÄS MER
2. Single Phase Active Power Factor Correction Converters - Methods for Optimizing EMI, Performance and Costs
Sammanfattning : In this thesis, front-end solutions with single-phase power factor correction (PFC) capability are studied. The reduction of current harmonics using various PFC techniques is investigated and related to the EN 61000-3-2 standard. LÄS MER
3. Developing Computational Methods for Moored Floating Wave Energy Devices
Sammanfattning : Floating point absorbers are a common class of wave-power devices typically designed to move with large amplitude in energetic waves. This stands in sharp contrast to traditional marine design, where the wave-excited motions of the structure are preferably kept to a minimum. LÄS MER
4. Simulation of the progressive failure of brittle rock
Sammanfattning : The anisotropic response of a brittle rock due to the formation of cracks under general applied loads has been taken as a continuous phenomenon on a suitable macroscopic scale. The response is described by a continuum field variable called the "damage vector". LÄS MER
5. Buoy Geometry, Size and Hydrodynamics for Power Take Off Device for Point Absorber Linear Wave Energy Converter
Sammanfattning : Wave energy converters of point absorber type have been developed and constructed. Full scale experiments have been carried out at sea and electricity has been successfully delivered. Linear permanent magnet generators together with a subsea substation and buoys of various geometric shapes have been investigated theoretically and experimentally. LÄS MER
