Abstract

In this work, a dual flapping tidal current generator is developed and then validated in indoor and in-situ experiments. It is recognized from the indoor experiments that the dual flapping generation system is optimal at the reduced frequency, 0.125 in terms of power extraction. In the consecutive in-situ experiments, system power, 6.4kW and system efficiency 36.5 % are obtained. The dual power transmission, which is also developed for transferring the swing motion of the flappers to the rotational output shaft, is validated in the both experiments and amended into a simple and different arrangement.cy, 0.125 in terms of power extraction.
