Correction to the Taylor hypothesis in swirling flows

J.-F. Pinton , R. Labbé

We present experimental results on the analysis of turbulent velocity measurements in the flow that develops in the gap between two coaxial counter-rotating disks (von Kármán swirling flow). In the absence of a well-defined mean velocity we introduce the use of a “local Taylor hypothesis" to obtain spatial information from hot-wire measurement at a fixed location. The results axe in agreement with conventional open-flow experiments.
