TLDR
In this paper, a dual turbine wheel wave energy converter with a belt-drive transmission system is proposed to provide an amplified rotational speed to the generator, which can effectively absorb the load fluctuations or vibrations caused by sea waves, and a lumped parameter analytical model is developed where the Lagrange principle is applied to analyze the motion of the system and the computational fluid dynamics simulation is employed to determine the drag coefficients.About:
