This work focuses on Savonius turbine numerical modeling and mutual turbine interaction in a linear array farm. Two-dimensional Computational Fluid Dynamics modeling was carried out using the open source solver OpenFOAM. Results are compared with available experimental data and three-dimensional CFD modeling. The influence of main parameters, such as the distance between adjacent turbines, the wind incidence angle and the number of turbines is investigated and the linear array efficiency is defined. The obtained results show a performance increase as the distance between the turbines reduces, higher efficiency for small wind incidence angles, and a larger number of turbines
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
