Darrieus turbines are less efficient in highly turbulent tidal flows compared to axial flow turbines due to their inherent design limitations in handling fluctuating flow directions and velocities. Darrieus turbines, also known as vertical axis turbines, rely on the lift force generated by the flow of water over their curved blades as they rotate around a central axis. These turbines are omnidirectional, meaning they can accept flow from any direction without needing to be actively oriented. However, this omnidirectional capability becomes a disadvantage in turbulent flows. In turbulent flows....
