Abstract
- In this study, the flow speed distribution generated between two tidal stream power generators was visualized. A vortex with regularity was generated in the perpendicular direction of the blade rotation direction. It was observed that this could affect up to 10 to 12 times of blade diameter. On the other hand, in the case of the support structure and foundation, the vortex strength was lowered by more than 60%, and it was confirmed that both units had the same effect. Remotely Operated Vehicle(ROV) operating in a low vortex environment can be sufficiently controlled using the currently developed thrust-weight ratio. In the future, this study's results will be used to develop underwater robots for maintenance.
