Mass Flow in The Wave Energy Converters with Differential Pressure Storage Tanks

Abstract

Among the devices for sea energy use in order to obtain power to be poured to the net, the present article discusses the performing of the oscillating water column wave energy converters (OWC) of the type of differential pressure storage tanks with (DPST) to be mounted on the coast (shoreline) or offshore (nearshore), as an alternative of improvement over conventional designs. In the operation of these kinds of converters, it is required the constancy of the mass flow rate of internal circulation as average value over a reduced interval (dependent on the size of the tanks), therefore it is studied the conversion performance dependence for each of the tanks according to the pressure in each of them, concluding that it is possible to work in a wide range of performance while maintaining the performance transformation close to maximum
