Airflow rectification strategies

Definition

Airflow rectification strategies refer to methods used to manage and control the direction and flow of air in systems, particularly in oscillating water column (OWC) devices that harness wave energy. These strategies enhance the efficiency of air turbines by ensuring that air flows consistently in one direction, thereby maximizing energy extraction during the oscillations created by waves. By optimizing the airflow, these strategies improve the overall performance of OWC devices and contribute to more reliable energy generation.
