Offshore foundation systems are constantly evolving to meet the needs of new developments in energy sector. Moving into ever deeper water for hydrocarbon recovery or creating foundation systems for renewable energy sources, such as offshore wind Turbines (OWT) farms, creates specific challenges. Large fixed vertical tower structures are typically used to support OWT inducing complex loading on foundations as a result of combined wind, wave and self-weight loading effects, all of which must be accommodated within very small rotation envelopes and natural frequency band to allow the turbines to operate effectively. In this thesis, a hybrid foundation (H.F) comprising a …

Recently, many renewable energy (RE) initiatives around the world are based on general frameworks that accommodate the regional assessment taking into account the mismatch of supply and demand with pre-set goals to reduce energy costs and harmful emissions. Hence, relying entirely on individual assessment and RE deployment scenarios may not be effective. Instead, developing a multi-faceted RE assessment framework is vital to achieving these goals. In this study, a regional RE assessment approach is presented taking into account the mismatch of supply and demand with an emphasis on Photovoltaic (PV) and wind turbine systems. The study incorporates mapping of renewable …
Vortex Identification In The Wake Of A Wind Turbine Array, Aleksandr Sergeyevich Aseyev
Vortex Identification In The Wake Of A Wind Turbine Array, Aleksandr Sergeyevich Aseyev
Dissertations and Theses
Vortex identification techniques are used to analyze the flow structure in a 4 x 3 array of scale model wind turbines. Q-criterion, Δ-criterion, and λ2-criterion are applied to Particle Image Velocimetry data gathered fore and aft of the last row centerline turbine. Q-criterion and λ2-criterion provide a clear indication of regions where vortical activity exists while the Δ-criterion does not. Galilean decomposition, Reynolds decomposition, vorticity, and swirling strength are used to further understand the location and behavior of the vortices. The techniques identify and display the high magnitude vortices in high shear zones resulting from the …
