There are many types of Vertical Axis Wind Turbines (VAWT), the Wollongong design, originally conceived in Australia is a very interesting type, because it presents a gear mechanism with a high potential for commercial application.
Theoretically there are many options of gear configurations, and the relationship between the number of teeth of each gear (Gear Ratio = G) has an essential impact on the function of the Wollongong turbine. In order to establish the most suitable G for the construction of the turbine, a Numerical Analysis was carried out. Through this analysis it could be concluded that a G= -1/2 would be the best option to obtain an acceptable performance, which means a larger amount of positive work.
Once the best Gear Ratio was defined and could be substantiated by a Numerical Analysis, the Experimental Tests were the next step. First, a Savonius turbine was acquired which included a device to measure the voltage; this equipment was used for both turbines, in order to compare them under similar conditions. Some improvements were done to the Savonius VAWT; this consisted in the adaptation of pair of bearings to reduce the oscillatory movement, hence the efficiency would be higher. When the Savonius VAWT was in optimal conditions, the construction of the Wollongong VAWT was done through CAD and Rapid Prototyping (3D Printing) technology. The most important consideration regarding to the Wollongong turbine, beside the gear configuration, was that the measure equipment of the Savonius turbine will have to be adapted into this one.
Finally both turbines were compared, and the results revealed that the Wollongong VAWT was much more efficient than the Savonius VAWT, which indicates high potential for commercial application.
