Tóm tắt

A flush-mounted hot-film anemometer is used to investigate the transition to unsteady flow in a lid-driven cavity with a small amount of through flow. The quantitative measurements with the hot-film probe confirm the transition from steady to time-periodic state from previous flow visualization studies and show a second transition in the primary state from time-periodic to quasiperiodic flow and a transition to a state with a broad band of frequencies typical of a chaotic state. From these results, it is concluded that the transition to unsteady nonperiodic state in this system is through a torus bifurcation.
