The ability to reduce the frictional drag in turbulent flow in pipes and channels by addition of a small amount of a high molecular weight polymer has application in myriad industries and processes. Here, the drag reduction properties of the polyelectrolyte xanthan are explored in differing solvent

## Abstract Structural turbulence has been detected in dilute aqueous solutions of Polyox Coagulant (also known to be a highly effective drag‐reducing agent). The flow line which characterizes structural turbulence from its onset in the laminar region passes well into the fully turbulent region (Re

A model for the boundary layer of a fully-developed turbulent pipe flow is presented in which the boundary layer is assumed IO consist of lumps which are. defined as fluid elements of laminar flow with unsteady velocity profiles and random ages. A burst is considered as the sudden replacement of a l
