Abstract

This work presents an experimental study of recirculating flows downstream of a flat duct sudden expansion. Results of measurements of average and RMS quantities of the pressure P and the axial velocity U exhibit the asymmetry of the flow behind the sudden expansion as in the two-dimensional case.
