  1. 1. Textile architecture informed by wind

    Author : Erica Hörteborn; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; HUMANIORA; HUMANIORA; ENGINEERING AND TECHNOLOGY; HUMANITIES; HUMANITIES; Textiles; Research by design; Textile architecture; Kinetic architecture; Lightweight structures; Wind; Geometric expression; Knitted textiles;

    Abstract : Textiles in architecture is a field of great potential, which are worth to explore further. This thesis aims to show that the flexibility of the textile material could be better included in the architectural design, allowing it to adapt to forces, such as the wind, and viewing motion as a positive design feature.

  2. 2. Wind-turbine wake flows - Effects of boundary layers and periodic disturbances

    Author : Ylva Odemark; Jens Fransson; Per-Åge Krogstad; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; wind-turbine model; wind tunnel; porous disc; hot-wire anemometry; particle image velocimetry; blade element momentum method; large eddy simulations; actuator disc method;

    Abstract : The increased fatigue loads and decreased power output of a wind turbine placed in the wake of another turbine is a well-known problem when building new wind-power farms and a subject of intensive research. These problems are caused by the velocity gradients and high turbulence levels present in the wake of a turbine. READ MORE

  3. 3. Wave Loads on Offshore Wind Power Plants

    Author : Jenny Trumars; Chalmers University of Technology; []
    Keywords : ocean engineering; shallow water; fatigue; Non-linear waves; wave load; wind energy converter; perturbation theory;

    Abstract : The thesis gives a short introduction to waves and discusses the problem with non-linear waves in shallow water and how they effect an offshore wind energy converter. The focus is on the realisation of non-linear waves in the time domain from short-term statistics in the form of a variance density spectrum of the wave elevation. READ MORE

  4. 4. Combined Electrical Power Generation using Solar and Wind

    Author : Ingemar Mathiasson; Chalmers University of Technology; []
    Keywords : wave length bands; atmospheric transmittance; energy storage; Wind turbine; wind speed; quantum dots; electrical load.; extinction coefficient; silicon solar cell; solar cell;

    Abstract : The need for systems for renewable electrical power production is enormous worldwide.This applies to systems of varying size and capacity. From small systems for household purposes up to large systems for regional purposes. If possible, all systems should be linked in a common power grid. READ MORE

  5. 5. Development of Vortex Filament Method for Wind Power Aerodynamics

    Author : Hamidreza Abedi; Chalmers University of Technology; []
    Keywords : unsteady aerodynamic load; atmospheric turbulence; fatigue loads; Free wake model; forest canopy; wind turbine; vortex method; large-eddy simulation;

    Abstract : Wind power is currently one of the cleanest and widely distributed renewable energy sources serving as an alternative to fossil fuel generated electricity. Exponential growth of wind turbines all around the world makes it apt for different research disciplines. READ MORE
