WAVE INDUCED ORIFICE FLOWS

A vertical oscillating water column with orifice plates over the air chamber above the column is studied both theoretically and experimentally. The orifice plates simulate a wave energy turbine in energy conversion. Results show that the assumption of linear compressibility overestimates the spring effect of the air column, while the assumption of incompressibility underestimates the spring effect. In addition, the unsteady orifice damping is found to be far greater than the steady damping. Finally impedance matching is approximately achieved.
