In this study, asymmetric wake is produced by control of boundary layer separation with placing tripping wire on the surface of circular cylinders in towed or swung motion to suppress the nonrepeatability of fluctuating lift. The effectiveness of the suppression was evaluated by standard deviation of ensembly collected lift data at each towed distances or swung angles and flow visualizations. The results obtained by this study will be applied to the development of manipulator arms operated in water where effects of mechanical vibrations are insignificant in comparison of that of fluctuating fluid forces associated with vortex formation.}, pages = {1726--1733}, title = {静水中で運動を開始する円柱に作用する変動流体力(反復運動における変動揚力の非反復性の境界層はく離制御による抑制)}, volume = {67}, year = {} }
