Localisation of the laminar-turbulent transition at turbulence wedges on wind energy rotor bladesThe efficiency rate of a wind turbine is determined mainly by the ratio of lift and aerodynamic drag. The amount of drag is depending on the friction between the flow and the rotor blade surface. The first near surface laminar flow regime in the direction of the... » more

Contamination-dependent performance analysis of wind turbines by means of thermographic flow visualisationThe economic efficiency of a wind turbine essentially depends on the electric output power, which is first converted from the kinetic energy of the wind into rotational energy of the rotor. For this purpose, special lift profiles are used for the rotor blades,... » more
