Alexander Raul Mayer Forsting will present his first results on induction modelling and simulations at the “ Wake conference”, 9-11 June 2015 in Visby, Sweden.
Alexander Raul Mayer Forsting presents his abstract “Blockage of laterally spaced turbines” at the conference.
The change in the individual power coefficients for a laterally aligned row of
turbines over a single free turbine is studied in the context of varying inflow direction via
numerical simulations, where all turbines are rotating in-line with the main flow direction. The
problem definition is similar to that of many wind turbine testing sites and wind farms and
thus could potentially have implications regarding power curve alidation procedures. When
studying these effects, the size of the computational domain was identified to be detrimental.
Increasing the misalignment of the main flow direction with the row of turbines led to relatively
large variations in the power production across turbines. At the largest yaw of 45° it varied
from -1.1% to 2%. As a whole, the power production increased by 0.5% and was almost
independent of inflow direction.
