1. 1. Analytical prediction of turbocharger compressor performance: A comparison of loss models with numerical data

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Sergio Sanz Solaesa; [2016]
   Keywords : ;

   Abstract : One-dimensional models predict the performance of centrifugal compressor in short time, being a helpful design tool in the early design stages. They assume uniform flow through the compressor. Conservation of mass, momentum and energy and some empirical loss correlations are applied to estimate the real outputs. READ MORE

3. 2. WAKE EFFECT IMPACTS ON THE ENERGY PRODUCTION OF THREE WIND TURBINES IN CLOSE CONFIGURATION

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : MEHMET ÇAĞRI HEKİM; [2015]
   Keywords : Actuator Disc; Wind Power; WindSim; Wake Effect; CFD; Offshore Wind Power; Analytical Wake Models; Wake Impact Analysis; Wind Energy; Offshore Wind Farm;

   Abstract : With the rapid expansion of offshore wind power capacity in the world in the last decade, innovative offshore solutions are designed in order to meet the upcoming power capacity installations. As in all other energy sectors, offshore wind power has certain conditions that have to be met to increase the efficacy of the outcome. READ MORE

4. 3. Simplified modeling of wind-farm flows

   University essay from KTH/Strömningsfysik

   Author : Raphael Ebenhoch; [2015]
   Keywords : Wind tunnel; Blockage effect; Numerical wake model; Linearized RANS; Linearized actuator-disc theory; Internal boundary layer; Dispersive stresses; Simplied CFD model;

   Abstract : Abstact: In order to address the wind-industry's need for a new generation of more advanced wake models, which accurately quantify the mean flow characteristics within a reasonably CPU-time, the two-dimensional analytical approach by Belcher et al. (2003) has been extended to a three-dimensional wake model. READ MORE

5. 4. Park optimization and wake interaction study at Bockstigen offshore wind power plant

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Jan Borràs Morales; [2014]
   Keywords : Wake; Wind power; Offshore; Analytical models; Experimental validation; Atmospheric stability; Layout optimization;

   Abstract : Losses for wake effects in offshore wind farms represent about 10% to 20% of the park annual energy production. Several analytical wake models have been developed and implemented to predict the power deficit of a wake-affected wind turbine. READ MORE

6. 5. An Aeroelastic Implementation for YachtSails and Rigs

   University essay from KTH/Marina system

   Author : Aron Helmstad; Tomas Larsson; [2013]
   Keywords : ;

   Abstract : An aeroelastic model has been developed to determine the elastic response of sailing yachts’ rigs and sails due to the aerodynamic pressure induced on the sails by the wind. A vortex-lattice method (VLM) is used to determine the aerodynamic pressure. The structural response is calculated with a non-linear finite element method (FEM). READ MORE
