An Approach for the Dynamic Behavior of Hydrokinetic Turbines

Energy Procedia, 2015
AbstractThe power generation, using hydrokinetic turbine, has been significantly studied in recent years. Such importance is due to the use of clean energy source with low environmental impact. That kind of technology converts the kinetic energy transported by marine and fluvial currents into mechanical energy and, consequently in electrical energy ...
