Comparison of Torque Characteristics of Archimedes Wind Turbine Evaluated by Analytical and Experimental Study
This paper represents design and fabrication of small scale horizontal axis wind turbine adopting Archimedes
spiral rotor blade. A new type of yawing mechanism is introduced to sense the direction of wind and to turn the rotor in the
most appropriate direction to harness maximum amount of wind energy eliminating the application of electronic devices.
The aerodynamics characteristics and performance of Archimedes wind turbine were investigated on actual size of the rotor
blade using computational fluid dynamics (CFD) simulations and field test. The torque obtainedfor lower wind speed is
relatively high as compared to other type of wind turbine. The analytical value of turbine characteristics shows good
agreement with the experimental results.
