Abstract
Several forms of wave-energy devices are currently being developed which incorporate oscillating ducted-flows. A method of extracting energy from such flows has been suggested whereby fluid is allowed to spill over from the top end of the duct during some portion of the oscillatory cycle into an elevated reservoir from whence it is directed through a low-head turbine.
A mathematical model of this energy conversion system has been derived for simulation on a digital computer; and the results of the analysis are presented here in terms of the efficiency of operation relative to the optimum linear case. The simulation is repeated for a wide range of input conditions and operating parameters. The conclusions drawn from this work may be seen to have a wider application in the field of non-linear energy exchange in resonant mechanical systems.
