According to the design nature of the ASWT, the aerodynamic forces generated on the spiral blades are three-dimensional. So, it is important to clarify the aerodynamic forces generated according to the interaction between the wind and the spiral blade in the plan and the elevation views, as shown in Fig. 16.
They tested three spiral blades connected with an angle of 120° and with symmetric installation on the shaft. In that study, Archimedes'' spiral wind turbine blade outer diameter was 1500 mm, the blade thickness was 5 mm and the turbine length was 1500 mm. The authors used the design of blade NACA 6409 airfoil shape.
In this article, a new kind of equiangular spiral blade vertical axis wind turbine is designed on the basis of the diagonal spiral. The wind turbine is simply improved by changing the pitch angle, and the 110° pitch angle blade with better performance is selected through the comparison of the simulation calculation method.
In conclusion, it can be seen that when the blade pitch angle is 110°, four blades provide power for the wind turbine during rotation, and only two blades are subject to the main leeward resistance, so the aerodynamic performance is better than the other two types, which proves the rationality of the design.
Recently, many wind turbines have been used to extract power from wind, such as Archimedes Spiral Wind Turbine (ASWT). In the current work, experimental and numerical studies are performed to elucidate the effect of the blades'' thickness and the blade angles on the performance of ASWT.
