  4. 32. Shedding light on the bluff body wake instability

    Author : Renzo Trip; Jens Fransson; Charles Williamson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Abstract : The flow around a vehicle, for example, results in a large resistance and can generate a complex swirl pattern behind the body of the vehicle, which can lead to strong alternating lateral forces. There is therefore a clear need for more fundamental understanding of the instability of this so-called wake region, which arises behind bluff bodies. READ MORE

  5. 33. Numerical computations of wind turbine wakes and wake interaction

    Author : Karl Nilsson; Dan Henningson; Stefan Ivanell; Thorsten Lutz; KTH; []
    Keywords : ;

    Abstract : When wind turbines are placed in farms, wake effects reduce the overall power production. Also, turbine loads are significantly increased since turbulence levels are high within the wake flow. READ MORE

  6. 34. Medicine for Uncertain Futures : A Nigerian City in the Wake of a Crisis

    Author : Ulrika Andersson Trovalla; Jan Ovesen; Sten Hagberg; Rachel Spronk; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cultural anthropology; Kulturantropologi; Kulturantropologi; Cultural Anthropology;

    Abstract : The Nigerian city of Jos used to be seen as a peaceful place, but in 2001 it was struck by clashes that arose from what was largely understood as issues of ethnic and religious belonging. The event, which would become known as ‘the crisis’, was experienced as a rupture and a loss of what the city had once been, and as the starting point of a spiral of violence that has continued up to today.

  7. 35. Wind turbines over a hilly terrain: performance and wake evolution

    Author : Ann Hyvärinen; P. Henrik Alfredsson; Antonio Segalini; Leonardo P. Chamorro; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; wind turbines; complex terrain; wind-tunnel measurements; Strömningsmekanik; vindturbiner; komplex terräng; vindtunnelmätningar; Engineering Mechanics; Teknisk mekanik;

    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.
