Experimental Analysis of Vortex Turbine Performance on Changes in Variation of Angle of Attack and Flow Rate

Abstract


A vortex turbine is a turbine that utilizes an artificial vortex to rotate the turbine blades and then converts it into rotational energy on the shaft. The process is that water from the river flows through the inlet to the turbine tank which is circular in shape and in the center of the bottom of the tank there is an exhaust channel. As a result of this exhaust channel, the water flow will form a vortex. In the design that has been carried out, to determine the maximum output of the performance of the vortex turbine is to vary the shape of the angle of attack of the vortex turbine blades, namely angles of 30°, 45° and 90° and the flow rate of 0.006 m3/s, 0.0083 m3/s and 0.01 m3/ s. So that the maximum power and efficiency is obtained from the design. Small scale vortex turbine design and testing the effect of blade angle of attack on power and efficiency. Experimental tests have been carried out on a vortex turbine by varying the angle of attack. The results showed that the highest power produced was 6.26 Watt at an angle of attack of 90o with a flow rate of 0.01 m3/s. The highest efficiency is found in the variation of the angle of attack of 90° with a flow rate of 0.006 m3/s and an efficiency of 19.4% is obtained.
