Abstract: | The flow fields for a sphere sedimenting through a Newtonian and two non-Newtonian liquids near a wall in a square tank are
investigated using 3-D stereoscopic particle image velocimetry (PIV) and line integral convolution (LIC) methods. The PIV
data were taken using an angular stereoscopic configuration with tilt and shift arrangements for the Scheimpflug condition
and a pair of liquid correction prisms. Data were recorded from planes perpendicular and parallel to the wall for each fluid
case over a range of distances from the wall. The PIV and LIC results highlight significant differences in the wake structure
for all three cases. Out of plane flow was also found to persist up to two sphere diameters downstream in the wake for all
cases. |
