Low-frequency flow fluctuations downstream of a sudden enlargement in a circular tube.

- Abstract
The low-frequency structure of the turbulent flow downstream of a sudden enlargement in a circular tube, after the flow has reattached to the wall, is studied. In a cross-section of the wide part of the tube beyond the reattachment point the total pressure is synchronously measured using radial and azimuthal rakes equipped with Pitot probes. The values of the coefficient of spatial correlation between the total-pressure fluctuations are considerably different for the azimuthal and radial directions. Under the assumption that the total-pressure loss in a fluid particle is conserved after flow reattachment to the wall, the azimuthal and radial components of the total-pressure fluctuations are estimated on the basis of the measured data.
