 note = {一様流れの中で角振動する円柱まわりの流れの様相および円柱に働く流体力などを数値解析(レイノルズ数Re=40～80)ならびにかなり広いレイノルズ数範囲(Re=40～10^4)にわたる実験によって求めた.すなわち,数値解法の精度などを吟味したあと,数値解析による抵抗や変動揚力の値は実測値とよく一致することから,本数値解法および実験の妥当性を確認した.そして角振動する円柱まわりの流れの様相とくに流れのはく難点の移動と変動揚力の変化は互に同位相で両者の間に深い関連性があることを見い出した.さらに円柱の振動とカルマン渦列との間のいわゆるsynchronization現象の様子を明らかにした.そして静止および角振動する円柱に働く変動揚力はRe=10^2～10^4の範囲ではほとんどレイノルズ数にはよらないことがわかった., To examine some aerodynamic characteristics of a circular cylinder located in a uniform viscous cross-flow, the authors have carried out some numerical calculations of the unsteady viscous flow around a cylinder and further some experiments by towing a test model in water or oil. Then the results are summarized as follows; 1) There can be seen a good agreement between the calculated values and the measured ones of aerodynamic forces exerted on a stationary or oscillating cylinder at the range of small Reynolds number, Re=40～80. 2) According to the numerical calculations, the points of flow separation on an oscillating cylinder are found to behave in the same phase with the fluctuation of lift force. 3) Such unsteady forces acting on an oscillating cylinder can be measured over the wide range of Reynolds number, Re=40～15,000, showing the phenomenon of synchronization at a certain range of ratio of the frequency of forced oscillation to that of Karman vortex street for a stationary cylinder. 4) Regarding the experiments, the unsteady aerodynamic forces exerted on a stationary or oscillating cylinder are found to be weakly depended upon Reynolds nnmber, 資料番号: SA0125425000},
