- 論文の詳細を見る
Experiments have been conducted on turbulence-induced vibration of a circular cylinder in water flow with supercritical Reynolds number ranging from 3×(10)^5 to 3×(10)^6. Based on the power spectral density of cylinder vibrations measured at several Reynolds numbers, fluctuating force coefficients, Strouhal number and correlation length were evaluated. As a result, it was clarified that the prediction method based on the random vibration theory introducing the correlation length has sufficient margin for actual turbulence-induced response.
