| Summary: | This study uses computational fluid dynamics (CFD) with the help of ANSYS Fluent
version 16 software to analyze the power coefficient of the Savonius-Darrieus combination
turbine with the addition of coupling mechanism. The turbine used in this study is a twobucket
Savonius and three-bladed Darrieus wind turbine. There are two cases of simulation
in this study, the first one is when the coupling is engaged and the other one is when the
coupling is disengaged. The power coefficient of engaged coupling simulation was compared
to the power coefficient of disenganged coupling simulation which have already been
validated.
ANSYS Fluent version 16 have been validated so it can be used to simulate
combination wind turbine. The result of the simulation after the coupling mechanism is added
shows an increase in power coefficient as mush as 9.3% on tip speed ratio 3, which is from
0.2761 to 0.3020. The coupling mechanism added on this research is selected with weighted
decision matrix where the weight distribution was made with hierarchy tree. The scoring
shows that the over-run clutch as the best coupling mechanism to be added to the combination
wind turbine with the total score 4.45 from maximum score 5.
