Flow-induced orientational change of aqueous solution of polymer after an abrupt expansion in planar channel flows

Flow-induced orientational changes of an aqueous polymer solution in planer channels have been studied utilizing optical rheometric technics. Two kinds of 1:4 abrupt expansion channels with the same width and different heights of 1 mm and 0.2 mm were tested in the experiments. 0.5 wt% xanthan gum so...
