Two porous deflectors were placed upstream of the wind turbine and the porosity, position, angle and length of one of the deflectors was optimized using numerical simulations. The performance of the turbine improved from 27% to 35%.

Suggested a guideline for performing stable and more accurate numerical simulation with proper turbulence model to minimize computational costs at different tip speed ratios.
