Abstract
In order to design a wave energy generate system, a 6-Degree of freedom motion analysis technique was applied to the three-Dimensional CFD analysis on two floating body and the behavior was interpreted according to the nature of the incoming wave. The waves are generated by the same type of wave in the model of tank using the piston type, but due to the shallow water that is generated from the bottom of the wave energy is attenuated by Ekman boundary layer. According to the wavelength of waves generated by the result of evaluating the behavior of floating body, it is concluded that 0.3m is the maximum amplitude of wavelength of 5m, and 0.15m is the minimum amplitude of wavelength of 1m. 1.06m is the maximum distance between the two floaters of wavelength of 6m.
