Abstract
In this study, the structure of fluctuating surface pressure acting on a fixed circular cylinder was investigated by computational fluid dynamics and POD analysis. Examinations of effects of member length in the analysis domain and member end boundary gives to fluctuating surface pressure acting on a fixed circular cylinder by numerical calculation were carried out. As results of this study, it was found that the fluctuating surface pressure acting on a fixed circular cylinder was affected by cylinder length and boundary conditions around the end of the cylinder. Moreover, POD analysis indicated that the fluctuating surface pressure acting on a fixed circular cylinder had symmetric and asymmetric mode shapes along the cylinder axis.
