Oscillatory pipe flow: A comparison between predicted and observed displacement profiles

  • 52 Accesses

  • 4 Citations

Summary

In this work a carefully calibratedWeissenberg rheogoniometer has been used to provide oscillatory rheological data on a 0.5% (aq.) polyacrylamide solution. These data have been corrected for all known imperfections and then used to predict oscillatory pipe flow displacement profiles. These profiles are compared with directly observed profiles obtained from an equally carefully calibrated pipe flow apparatus. There is agreement between the main features of the two sets of profiles. This work, like prior related work (11, 12, 13) does not involve the use of specific rheological models.
