Among the various potential renewable energy sources, sea waves offer significant potential, which can be harnessed using wave converter (WEC) devices such as overtopping converters. These operate by directing incident up a ramp into reservoir. The water then passes through turbine coupled with an electrical generator before returning to ocean. Thus, present study deals geometrical evaluation of WEC, where influence ratio between height and length device (H1/L1) on amount mass (M) that...
Irregular wave generation in numerical simulations is critical for accurately modeling realistic sea conditions, which essential coastal and offshore engineering applications, such as energy conversion.
