Özet

This study is related to the newly developed and patented turbo solenoid turbine system. In this context, a numerical study was conducted on turbines with Darrieus, Gorlov and Lucid (R) configurations. As a result of the tests made on turbines with a NACA0018 aerofoil profile, the Lucid (R) turbine produced the highest moment and also highest pressure loss. Although a 10 degrees twisted aerofoil Gorlov turbine produced 31.3% less moment than the Lucid (R) turbine, it also caused 51.4% less pressure loss. Also, it was observed that a Darrieus turbine with NACA0021 profile produced 1.5% less moment and 3.3% more pressure loss than a NACA0018 profile and turbine with NACA0015 profile, which produced 9% more moment and 1.4% more pressure loss than NACA0018.On the performance impact studies of the aerofoil twist angle, 20 degrees twisted Gorlov turbines produced 19.1% more moment and 5.5% less pressure loss than a 10 degrees twisted aerofoil turbine. Finally, a 20 degrees twisted Gorlov turbine with NACA0015 aerofoil profile was analyzed. Following the studies, it was observed that the 20 degrees twisted Gorlov turbine with NACA0015 aerofoil profile gave the best result by creating a 49.3% less pressure loss, in spite of only producing 4.7% less moment than the Lucid (R) turbine.
