【摘要】 本文介绍应用光滑柱体在静水中作简谐振荡,测量振荡流中的圆柱流体动力系数的试验研究。试验是在上海交通大学流体力学试验室的水槽中进行的,应用直径为0.10、0.08.0.06、0.04、0.02米的圆柱,作频率为0.125到0.25赫兹的大振幅振荡,测量其水平方向和垂直方向的力。对测量得到的流体动力时间历程进行的分析表明,这一类测量方法,可以得到和Sarpkaya应用U型管测量得到的相同精度的结果。更多还原

【Abstract】 This paper describes an experiment of an oscillating cylinder in the fluid to measure the hydrodynamic coefficients. The results obtained demonstrate that although the principle of the test is somewhat different from those used previously it gives the reliable results. The apparatus, transducer as well as the method of analysis used in this test are described in detail in the paper. The measured results are shown in graphics.更多还原
