曾经年少爱追梦摘要：An analysis of the velocity profile and pressure drop relationships for turbulent flow of fiber suspensions through smooth tubes was evaluated experimentally over a range of flow rates, tube sizes,

This work shows that drag reduction in the systems, in marked contrast to that in viscoelastic polymeric fluids, involves process in the turbulent core of the velocity field. As a result the drag reduction achieved is independent of the scale of the system. The implications of the results with respect to rates of heat and mass transport are considered in a preliminary way. The measurement of such transport rates, and of the turbulent velocity profiles in dilute suspensions, is en to be of mechanistic interest.
