Abstract

A ducting system is a practical means of perhaps improving wind turbine productivity. This paper is aimed to investigate a potential strategy for enhancing the performance of vertical-axis wind turbines. It is distinguished by the addition of a convergent duct, which makes it easier to impart higher flow rates. The system was methodologized and simulated analytically and numerically as well. To do so, a computer program written in MATLAB is adapted to simulate the viability of the system. The performance was numerically processed utilizing ANSYS-FLUENT 17.2. The result shows that the average power coefficient and velocity enhanced for a convergent duct with a converging angle of 20º by 32.2 % and 47.7% respectively for the Savinus wind turbine. Also, the result shows that slight pressure decreased by 0.2077% compared with velocity increase. Results revealed an acceptable impact on the wind turbines. This technology may be effectively employed in gates and urban sites with a roughly low wind speed regime.
