1. Wind turbines over a hilly terrain: performance and wake evolution
Abstract : The aim of this licentiate thesis is to investigate wind-turbines placed in a complex-terrain environment. This is done by studying the flow around small-scale wind-turbine models placed over a landscape model with hills, and by comparing the results with corresponding data obtained over a flat terrain model.

2. Knitted architecture and wind: Designing loosely fitted architectural textiles for interaction with wind
Abstract : Utilising the textile’s ability to adapt to external forces such as the wind could lead to the creation of new design expressions and functional features within architecture. Prompted by architectural potentials of textiles deliberately designed to move and flex, this thesis aims to explore and demonstrate how such knitted textiles could contribute to enriched aesthetic expression and improved performance of architectural elements placed in windy environments.

3. Impact of Icing on Wind Turbines Aerodynamic
Abstract : Wind energy covered 11.6% of Europe electricity demand in 2017. Region with cold climates represent a strong potential for wind energy companies because of their sparse population and proper wind conditions. The global wind energy installations in cold climate regions is forecasted to reach a capacity of 186 GW by the end of 2020. READ MORE

4. Numerical study on instability and interaction of wind turbine wakes
Abstract : The optimization of new generation of the wind farms is dependent on our understanding of wind turbine wake development, wake dynamics and the interaction of the wakes. The overall goal of the optimization is decreasing the fatigue loading and increasing the power production of the wind farms. READ MORE

5. Evaluation and modeling of the flow in a slotted wall wind tunnel
Abstract : As vehicle manufacturers strive to shorten the development time of new models, an increasing share of the aerodynamic development work is shifted from wind tunnel testing of prototype vehicles to numerical simulations of virtual models. However, comparing measurements from the wind tunnel with numerical simulation data is not straightforward due to several interference effects occurring between the wind tunnel and the tested vehicle.
