Flow Patterns

Definition

Flow patterns refer to the organized movement of water within a body of water, particularly in relation to tidal streams. Understanding these patterns is crucial for optimizing energy conversion in tidal stream energy systems, as they influence the speed and direction of water flow, which directly affects the efficiency of energy capture by turbines and other devices.
