Abstract
The present study analyzes different arrangements of hydrokinetic types of turbines. Considering the experiment of the number of blades of the rotor and analyzing it from the method of experimental visualization of flow using the technique of smoke wire. The tests were performed with the flow velocity of 5 m/s of the wind tunnel to the turbine rotor of 230 mm of diameter. With the smoke visualization method, it was possible to verify the behavior of the turbine before the flow and to approach qualitative properties of the phenomena inherent to the interaction of the components of the turbine with the flow. The characteristics of the flow were analyzed by two different turbine configurations: three-bladed turbine and four-bladed turbine. The characterization for the observed configurations shows the formation of blade-tip vortices and the influence of the generator hub on the fluid. The smoke wire technique used is also presented.
