Abstract

Flow-visualization measurements of the laminar flow in an expanded pipe with diameter-ratio 2 are carried out under the periodical unsteady condition. Flow transition to turbulence of 3 D structure is found to be related to mean Reynolds number, amplitude Reynolds number and frequency. Timevariations of the flow structures are also investigated.
