Paragraph starter
The research by Flannery, Holligan, and Soares (2014) highlights the effectiveness of using Computational Fluid Dynamics (CFD) modelling in conjunction with rapid prototyping to enhance the performance of small wind turbines. Their study demonstrated that a shroud attachment could increase energy yield by over 200% by accelerating airflow to the turbine blades, with CFD predictions validated by wind tunnel testing. This approach provides a strong precedent for using simulation and physical testing to iteratively optimize design elements for improved efficiency.
