Mielparque-tokyo), Minato-ku, Tokyo, Japan, In many fluid-structure-interaction problems, the added mass is one of important interests. In the present study, we propose a simple and efficient method to specify fluid-force coefficients of a three-dimensional oscillating object in viscous fluid. The solving method is based on a discrete singularity method DSM. Then, we apply the DSM to some three-dimensional basic objects such as square-cross-section cylinders with various aspect ratios. Furthermore, we conduct experiments, and reveal the fluid-force coefficients of them comparing between computations and experiments, which show good agreement., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630046036, レポート番号: JAXA-SP-16-008E}, pages = {349--358}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {High-speed computation and experiment on added-mass and viscous-damping forces acting on various oscillating 3D objects}, volume = {JAXA-SP-16-008E}, year = {2017} }
