1. 1. An evaluation of deterministic prediction of ocean waves using pressure data to assist a Wave Energy Converter

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Niclas Bassili; Douglas Eriksson; [2020]
   Nyckelord :Deterministic wave prediction; Pressure sensor; Weakly dispersive reconstruction method; Time to spatial data assimilation; High-order spectral method; Determinisk vågförutsägelse; Trycksensor; Weakly dispersive reconstruction method; Time to spatial data assimilation; High-order spectral method;

   Sammanfattning : Currently, existing devices for extracting electrical power from ocean waves all suffer from problems with low efficiency due to a lack of information about the incoming waves in advance. The complex dynamic nonlinear characteristics of the ocean make the prediction of these incoming waves a great challenge. LÄS MER

3. 2. Numerical Simulation of Wind Turbine Wakes based on Actuator Line Method in NEK5000

   Master-uppsats, KTH/Mekanik

   Författare :Wenjie Jin; [2013]
   Nyckelord :Wind Turbine; Wake Flow; Actuator Line Method; NEK5000; Trip Vortices;

   Sammanfattning : Nowadays wind turbines are clustered in wind farms and the wake development plays an important role in energy production and blade fatigue load of tubines. The actuator line method is an effective modeling approach that gives improtant wake flow characterstics of a wind turbine. LÄS MER
