Modelling and preliminary studies for a self-reacting point absorber WEC

This paper deals with the special case modelling, in both frequency and time domain, of a self-reacting wave energy converter where the reaction force is obtained using a damping plate. In order to take into account the viscous damping that arises on the plate due to the flow separation at the sharp corners, an additional non-linear term have to be introduce. The influence of this non-linearity is then evaluate in a qualitative manner and obviously it is found that we can not neglect it.
