 note = {First International Symposium on Flutter and its Application (May 15-17, 2016. Mielparque-tokyo), Minato-ku, Tokyo, Japan, Marine renewable energy is an important future energy source. For wave energy, a point absorber with an oscillating body is a well-known type of wave energy converter and its features are relatively simpler system and lower cost than other types of wave energy converters. Reactive control concept is important to achieve larger energy income, but large motion of the float by reactive control is matter. The understanding of the device's behavior is important for the design but the large motion of the float is difficult to predict by the numerical simulation. The numerical simulation of the point absorber's behavior is often based on the so-called “linear theory”. Linear problems are easy to analyze with BEM software like WAMIT, but nonlinear problems with the large motion of the float are difficult to analyze. CFD or FEM techniques will predict the nonlinear problems, but those techniques need the huge computer resources. In this study, the authors tried to simulate the large motion of the float using BEM and a fluid parameter table look-up technique is used. In the fluid parameter table look-up technique, several cases of the float's position are considered and fluid parameters for each case are calculated by BEM software. The calculated fluid parameters are kept in a memory and the time domain simulation program uses the parameters correspond to the position of the float. Using that technique, the numerical simulations of wave energy converters with cylinder shape float and tapered shape floats are demonstrated., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630046057, レポート番号: JAXA-SP-16-008E},
