Upstream Wake Effect On The Performance Of The Horizontal Axis Tidal Current Power

The rotor initially converting the flow energy into rotational energy is a very important component that affects the efficiency of the entire system. The rotor performance is determined by various design variables. The power generation is strongly dependent on the incoming flow velocity and the size of the rotor. To extract a great quantity of power, the tidal current farm is necessary with multi-arrangement of devices in the ocean. However, the interactions between devices also contribute significantly to the total power capacity. Therefore, the rotor performance considering the interaction problems needs to be investigated to maximize the power generation in a limited available area. The downstream rotor efficiency is to be affected by the wake produced from upstream rotor. This paper introduces the performance of downstream rotor being affected by wakes from upstream rotor which demonstrates the interference for various gabs between devices.
