AI Technical Summary
Traditional OWC devices suffer from low aerodynamic efficiency and large aerodynamic power fluctuations due to the use of self-rectifying bidirectional turbines, which affects energy conversion efficiency and output power stability. While the introduction of a one-way valve in closed-loop PTO improves flow characteristics, it also leads to energy loss.
A dual-chamber structure is introduced into the closed-loop PTO device. By adjusting the phase difference of the water column movement and combining the advantages of closed-loop PTO and dual-chamber, the high-pressure chamber and low-pressure chamber are designed to be connected to the oscillating water column chamber respectively, forming a stable unidirectional airflow to drive the unidirectional turbine.
It effectively reduced the aerodynamic power fluctuation of the turbine and improved the overall energy harvesting efficiency. The device structure was optimized through numerical simulation, which improved the energy conversion efficiency and power stability.
