| Summary: | 碩士 === 國立中央大學 === 物理研究所 === 93 === We present an experimental characterization of dynamics of a cylindrical rod in a vertically flowing soap film. The rod is setup to be capable of rotating freely in the soap film. The Steady(S), Fluttering(F), and Rotating(R) motions of the rods are observed, and there are two kinds of transitional motions –Fluttering-Rotating(FR) mix, and Dull(D). The dynamics of the flow field in the soap film and the transitions between different rod motions have been studied under different physical parameters
of the rod and soap film. We find out a dimensionless parameter(P) to describe the
transitions of the rod’s motions, which in the vertically flowing soap films have no concern with the moment of inertia.
