Wind tunnel tests were conducted for the performance of tornado-type wind turbines (TTWT) with radial inflow supply from incoming wind. It was shown that the radial inflow supply was necessary for intensifying a vortex in the wind collecting tower and, consequently, for enhancing the power efficiencies, C /SUB p/, of the wind turbines. Maximum C /SUB p/ (based on turbine disk area) of 3.8 and 9 was obtained for circular- and spiral-shaped towers, respectively, as compared to 0.4 for conventional windmills. With the radial inflow supply, the maximum C /SUB p/ was increased about 100% for the circular model but only 15-30% for the spiral model since the spiral model provides the inflow effect by itself.
