Abstract:
Overtopping breakwater for energy conversion (OBREC) is integration between breakwater
and wave energy converter (WEC) that allows incoming waves to be stored in the reservoir.
The higher the overtopping amount collected in a reservoir, the greater the energy generated
will be. Hence, most of the overtopping concept has attempted to maximize the inclusion of water in
the reservoir by optimizing geometrical parameters, particularly the ramp angle. However, the studies
corresponding to ramp shapes geometries have not been adequately reviewed. Most studies only
focused on the usage of linear overtopping ramp shape. There is still limited knowledge on the
influence of different ramp shape parameters towards the overtopping wave. Thus, this paper
aimed to push the border of available knowledge by investigating the influence of the ramp shape
parameters to the overtopping wave discharge through simulation and experimenting approaches.
Seven different ramp shapes have been tested under Malaysia’s wave condition and a new ramp
shape parameter allowing for maximized overtopping wave on OBREC is presented.
