As a system using a conventional unidirectional air turbine in oscillating water column (OWC) based on a wave energy plant, a twin unidirectional impulse turbine topology has been suggested in previous studies. However, the average efficiency of the suggested twin turbine is considerably lower than that of a conventional unidirectional turbine in this topology because reciprocating air flow can't be rectified adequately by a unidirectional turbine. In order to improve the efficiency, using fluidic diode is discussed. The fluidic diode characteristics under steady flow conditions were investigated numerically by computational fluid dynamics. The effect of fluidic diode geometry on the performance were discussed in this study.
