An experimental study of the decay of turbulent puffs in pipe flow. (English) Zbl 1221.76009
Summary: As reported in a number of recent studies, turbulence in pipe flow is transient for \(Re<2000\) and the flow eventually always returns to the laminar state. Generally, the lifetime of turbulence has been observed to increase rapidly with Reynolds number but there is currently no accord on the exact scaling behaviour. In particular, it is not clear whether a critical point exists where turbulence becomes sustained or if it remains transient. We here aim to clarify if these conflicting results may have been caused by the different experimental and numerical protocols used to trigger turbulence in these studies.
