Studies on the Shore-Fixed Air Chamber for Wave Power Generation. Pressure and Flow Direction Control for a Turbine with a Swaying Valve.

The air chamber system is a kind of method for transformation from wave energy to mechanical energy. In this system, wave energy operates periodically in the wave power generation plant. In order to improve this system, we propose a new technology with one-way flow and restriction of turbine input. The former is applicable to an impulse turbine, and the latter saves the excess power from the air chamber. In this system, the air duct has a bypath with a turbine. Pressure and flow direction are controlled with only one swing plate valve in the air duct. This paper describes both experimental results at a site of sea-side, and the analytical result of the plant performance.
