Experimental investigations of number of blades effect on archimedes spiral wind turbine performance

Abstract

This study investigates the effect of blade numbers on the performance of Archimedes Spiral Wind Turbines (ASWT), a low-speed axial flow turbine with an Archimedean spiral blade design. Experimental tests and numerical simulations were conducted to evaluate power generation and fluid flow behavior. Results revealed that a three-blade ASWT achieved optimal performance, producing 158.5% more power than the four-blade configuration. The findings highlight the significant influence of blade numbers on ASWT efficiency, offering insights for improving wind turbine design in urban renewable energy applications.
