HYDRAULIC MODEL TEST OF WAVE ENERGY CONVERSION
Keywords:
Oscillating Water Column (OWC), orifice, reflectorAbstract
This paper reports the experimental study of wave energy conversion system. The
Oscillating Water Column (OWC) has been selected as the primary object of the
experimental research. More over, the experimental is a serial research for studying the
performance of the OWC. Different models of the OWC have been tested in the previous
research. The research reported in the paper tried to apply the reflector in the rear
bottom of the cylinder to improve the poor efficiency in the previous models test. The
experiment is performed by placing the model in the flume tank and slammed by water
wave varied at some wave heights and periods. The reflector posit ion can be changed its
slope to obtain the best position for the maximum efficiency. The experimental result
indicated that efficiency of the owe with reflector is better than the OWC without
reflector. The model with reflector slope of 45° produced better efficiency compared to
the remaining slope. The efficiency for model with reflector increases almost double than
the efficiency ofthe model without reflector (previous experiment).
