Experimental Study of The Fan Turbine Performance in Oscillating Water Column with Airflow System in Venturi Directional

The Indonesian Ocean Energy Association has ratified the potential for ocean wave energy in Indonesia with a theoretical of 141,472 Megawatts. Unfortunately, this vast not yet been utilized optimally seas. technology developed rapidly various countries worldwide. One most famous power generation technologies is Oscillating Water Column (OWC), which utilizes airflow from waves oscillating movement. Inspired by OWC, an innovative model was designed using simpler fan turbine because it directly integrated electric dynamo and internal flow system venturi tube can increase airspeed based on concept continuity theory. experiment's results succeeded creating up down movements high tide 15 cm low 12 cm. oscillations produce gusts air speed 1.56 m/s. final result obtained performance average rotation 42.191 rpm, voltage 0.809 volts, more optimal efficiency 67.9%.
