Abstract: This study presents experimental results of oscillating water column (OWC) testing with unidirectional water flow system. The main objectives of this research is to investigate the effect of different configurations of submerged multi-chamber of OWC by integrating non- return valve panels in order to determine optimal parameters. Through the analyses, the following parameters are evaluated as conversion efficiency indices: the incident wave power, the area of valve panels of first column and second column, the wave height in the first column and the second column and the flow rate of the outlet of device. The results show that there is an optimal operating point that depends on the ratio between the area of valve panels in the first column and the second column. The peak value of conversion efficiency is found to be 47 percent at the valve panel area ratio of 1:1 under the condition of the maximum incident wave power.
