초록

This paper deals with the internal oscillating flaw in air chamber and duct of an OWC-type wave energy converter by numerical analysis using commercial CFD code, FLUENT. Whole oscillating flaw from OWC-type chamber to outlet through duct was solved by unsteady analysis in order that performance of wave energy conversion was made better. Results show that whole oscillating flaw field of this system in unsteady condition. Duct shape at setting place of turbine is curved with elbow, because profile of inlet condition to turbine is important in its efficiency. This paper is found internal flaw in air chamber and duct. Also, this research was found effect of duct shape.
