Small wind turbines (SWTs) are essential for harnessing renewable energy, particularly in developing regions where energy demands significant. They provide a sustainable solution to meet the critical needs of these areas. However, low Reynolds number (Re) airflow characteristics can pose challenges, making optimising airfoil shapes enhancing aerodynamic performance and capture. This study offers thorough analysis six different profiles within Re range 50k 500k. Modifications thickness-to-camber ratio (t/c) were strategically targeted improve efficiency structural viability. Using QBLADE software, we evaluated design alterations optimise lift coefficient (CL), drag (CD), stall angle attack (αstall) lift-to-drag (L/D). The revealed significant improvements maximum power (Cp.max), with modified BW-3 achieving Cp.max 0.441 at 500k – remarkable 40.5% increase over baseline values. consistent enhancement across various emphasises impact capture reinforcing feasibility SWT applications diverse operating conditions, along material savings that lead lighter turbine (WT) blades.
