The present work aims to develop a computational model investigating turbulent flows in problem that simulates an oscillating water column device (OWC) considering Savonius turbine the air duct region. Incompressible, two-dimensional, unsteady, and were considered for three different configurations: (1) free inserted long large channel verification/validation of model, (2) enclosure domain mimi...

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 moveme...

This study presents benthic data from 12 samplings from February to December 2010 in a 28 m deep channel in the southwest Baltic Sea. In winter, the distribution of solutes in the porewater was strongly modulated by bioirrigation which efficiently flushed the upper 10 cm of sediment, leading to concentrations which varied little from bottom water values. Solute pumping by bioirrigation fell sha...

This paper presents the results of laboratory tests on a hybrid wave energy converter concept, O2WC (Oscillating-Overtopping Water Column) device. The proposed device aims at providing an alternative to classical OWC storing part highly energetic sea states in second chamber atmospheric pressure, through overtopping phenomena. In this way, maximum airflow rate and air pressure are reduced, poss...
