摘要
Using a special analogy to a parametrically forced mathematical pendulum with energy flux, it is attempted here to model the vortex wake in a fluid due to the movement of a cylindrical solid body. We also show that the path taken by certain fluid particles represents a homoclinic soliton and corresponds to a spacial separatrix. This in turn may lead through deterministic fluctuation to diffusion-like chaotic motion.
