Studies on free surface flow of concentrated suspension in open channels and rotating cylinders

Abstract

Free surface flow of concentrated suspension has been studied in open channel and rotating cylinders at low Reynolds number flow In this work the wall slip was characterized through flow visualization experiments The conventional rheometers and Couette cells has been used for determining slip velocity for suspension of smaller particles However characterization of wall slip for suspensions of larger particles such as debris flow concrete mixtures etc cannot be performed in conventional rh
