Abstract

Hasil penelitian ini dilakukan untuk menganalisis kinerja turbin vortex pada variasi sudut stagger 15° dan 20°. Turbin vortex dengan sudut stagger 15° merupakan variasi yang memiliki performa paling optimal pada kapasitas 500 lpm yaitu putaran 60 rpm memiliki torsi sebesar 2,15 Nm, daya sebesar 13,53 watt dan efisiensi sebesar 32,3%. . Pada kapasitas 400 lpm, putaran 60 rpm, turbin vortex dengan sudut stagger 15° memiliki torsi sebesar 0,997 Nm, daya sebesar 6,26 watt dan efisiensi sebesar 18,6%. Pada kapasitas 500 lpm, turbin vortex dengan sudut stagger 15° mampu menghasilkan koefisien daya maksimum sebesar 0,32 pada tip speed ratio 1,93. Sedangkan pada kapasitas 400 lpm turbin vortex dengan sudut stagger 15° mampu menghasilkan koefisien daya maksimum 0,20 pada tip speed ratio 2,89. Dan pada kapasitas 400 lpm turbin vortex dengan sudut stagger 15° mampu menghasilkan koefisien daya maksimum sebesar 0,19 pada tip speed ratio 3,66.

The results of this study were conducted to analyze the performance of the vortex turbine at stagger angle variations of 15° and 20°. In order to obtain data on the performance of the vortex turbine in the experimental study, it can be carried out at certain loading variations, so that in this study a variation of the vortex turbine rotation was carried out in multiples of 20 rpm. 2. At a capacity of 500 lpm, the vortex turbine with a stagger angle of 15° is capable of producing a maximum power coefficient of 0.24 at a tip speed ratio of 1.93. Whereas at a capacity of 400 lpm the vortex turbine with a stagger angle of 15° is capable of producing a maximum power coefficient of 0.20 at a tip speed ratio of 2.44. And at a capacity of 450 lpm the vortex turbine with a stagger angle of 15° is capable of producing a maximum power coefficient of 0.22 at a tip speed ratio of 2.16.
