Abstract

Detailed experimental results are presented for the steady separated flow past a variety of bluff objects. Included in this work are measurements of: rear stagnation point pressure coefficients; the pressure distribution along the base of a backward-facing step; velocity profiles within the circulating wake-bubble as well as in the outer flow; lengths, maximum widths and vortex centre locations of the corresponding wake-bubbles; and the local shear stress along the surface of a circular cylinder. In every case, the experimental data were found to be consistent with the theoretical model proposed by Acrivos et al. (1965) for the steady separated flow past bluff objects in the limit of large Reynolds numbers R.
