【Abstract】 For T/D = 1.75、2.5、3.5, the dynamic responses and the vortex shedding frequencies of a pair of elastic tubes with the same diameter subjected to liquid cross flow are studied experimentally. According to measurements, the frequencies and the displacement in the down stream transverse directions, which depend on T/D and V?, are given in the present paper. Meantime, Strouhal number for elastic cylinder is properly discussed.更多还原
