1. Fluid mechanical simulations and development for vertical axis turbines
Sammanfattning : The aerodynamics of vertical axis turbines is typically studied using streamtube, vortex or CFD models. This thesis focuses on the first two models, which are the computationally faster ones. LÄS MER
2. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development
Sammanfattning : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. LÄS MER
3. Aeroacoustic Prediction for Vertical Axis Wind Turbines
Sammanfattning : This thesis investigates the aerodynamic and aeroacoustic prediction of vertical axis wind turbines, using computational fluid dynamics simulations. Noise pollution from wind turbines is one of the disadvantages of wind energy, calling for strategies to reduce noise levels. LÄS MER
4. Aerodynamics of Vertical Axis Wind Turbines : Development of Simulation Tools and Experiments
Sammanfattning : This thesis combines measurements with the development of simulation tools for vertical axis wind turbines (VAWT). Numerical models of aerodynamic blade forces are developed and validated against experiments. The studies were made on VAWTs which were operated at open sites. LÄS MER
5. Aerodynamic Studies of Vertical Axis Wind Turbines using the Actuator Line Model
Sammanfattning : This thesis addresses the unsteady aerodynamics involved in the operation of vertical axis wind turbines (VAWTs). The main focus is to represent and understand the most relevant phenomena within the resulting flow pattern as the wake structure, loads on the different turbine components and the performance of the rotor.
