Abstract The so-called 20-20-20 targets for the European Union include a reduction in
greenhouse gas emissions by 20% compared to 1990, 20% of primary energy from …

Small Wind Turbines (SWTs) are promissory for distributed generation using renewable
energy sources; however, their deployment in a broad sense requires to address topics …

Small wind turbines usually operate in sub-optimal wind conditions in order to satisfy the
demand where it is needed. The aerodynamic performance of small horizontal axis wind …

In this work, we investigate the characteristics of wind turbine wakes for three different blade
designs (ie the NREL-Ori, NREL-Root and NREL-Tip designs, where the NREL-Ori refers to …

Horizontal axis wind turbines (HAWTs) are being widely used for green energy generation.
Hence, aerodynamic performance enhancement of these machines is a key point for their …
