1. 16. Forest Simulation with Industrial CFD Codes

   University essay from KTH/Strömningsfysik

   Author : Petter Cedell; [2019]
   Keywords : RANS; LES; WindSim; CFD; Forest Model; Turbulence; FVM;

   Abstract : Much of the planned installation of wind turbines in Sweden will be located in the northern region, characterized by a lower population density so that problems related to sound pollution and visual acceptance are of lower concern. This area is generally distinguished by complex topography and the presence of forest, that significantly affects the wind characteristics, complicating their modelling and simulation. READ MORE

3. 17. Nanogrid For Renewable Off-GridSystem : Nanogrid For Renewable Off-GridSystem

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Chukwuebuka Louis Onyia; [2019]
   Keywords : ;

   Abstract : Power grids utilize large central generating stations which entails the use of long transmission lines to deliver power to consumers. This approach poses some challenges such as line loses and carbon dioxide (CO2) emission into the environment from the burning of fossil fuels from such large generators. READ MORE

5. 19. A COMPARISON OF THE OBSERVED WAKE EFFECT WITH SEVERAL WAKE MODELS USING BOTH ANALYTIC AND CFD SIMULATION METHODS - FOR THE CASE OF BLOCK ISLAND OFFSHORE WIND FARM

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Robbie Pratt; [2019]
   Keywords : Block Island Wind Farm; Offshore Wind Power; Wake Effect; Wake Modelling; WindPRO; WindSIM; Openwind; CFD modelling.;

   Abstract : This paper sets out to analyze the observed wake effect at Block Island Wind Farm. A comparison is made between several wake simulation methods and the observed data at Block Island using analytic and CFD (Computational Fluid Dynamics) modelling methods. READ MORE

6. 20. A Study and Modelling of Chaff Clouds Affected by Wing-Tip Vortices

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Jonathan Persson; Jakob Warlin; [2019]
   Keywords : chaff study modelling aerodynamics wing-tip vortices; Technology and Engineering;

   Abstract : Chaff are thin strips of either metal or metal coated fibres used as countermeasures against radar. When deployed from an airplane, the turbulence and wing-tip vortices from the airplane disperse the chaff into a chaff cloud, which may appear as a false target and jam the radar. READ MORE
