A distributed parameter model of a collapsible tube, in which no effect of separation occurring in the collapsed part is considered, is numerically analyzed by means of the SIMPLE method. Transient flow behaviors, stability of steady flows and self-excited vibrations are investigated. Furthermore, the wave propagation in the tube is indicated as a 3-dimensional bird's-eye view with the temporal and spatial axes. The numerical results are consistent with experimental results.
