1. 1. Design Optimization of Savonius Wind Turbine using CFD Simulations

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Vatsalkumar Manavar; [2023]
   Keywords : Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

   Abstract : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

3. 2. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
   Keywords : CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

   Abstract : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. READ MORE

   Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE
