Abstract

An experimental investigation has been conducted in a lobed forced mixer with three different trailing edge configurations, using laser-Doppler anemometry, at a Reynolds number of 2.27 × 104. The three trailing edge configurations under investigation have the shape of a square wave, a semi-circular wave and a triangular wave. The results for a velocity ratio of 1:1 indicate that the strength of the secondary flow shed by a lobe may not be the only parameter which determines the effectiveness of mixing, as previously suggested. The boundary layer thickness which grows along the side-walls of the lobe penetration and the subsequent shedding of the boundary layer to the wake region are of equal importance.
