Upstream Flow

It has been found experimentally that the turbulent pipe flow through a mitred, right-angle bend produces a downstream secondary circulation which does not conform to the twin-circulatory flow usually to be found in pipe bends. The secondary flow is dominated by a single circulation about the axis in either a clockwise or an anticlockwise sense, between which it switches abruptly at a low, random frequency. The phenomenon is explained in terms of the asymmetry of the inner wall separation and the turbulent axial circulation generated in the upstream flow.

Similarity Laws

The hydrodynamic aspects of drag reduction with additives are presented. The fundamental properties of this remarkable phenomenon are described. A brief history is outlined from anomalous results in pipe flow, through strange effects in the Texas oilfields and to the current research efforts. Correlation by means of the velocity similarity laws of turbulent flow is explained for drag reduction in pipe flow and for the boundary layers on bodies. The limits of drag reduction are also explained on the basis of the interactive similarity law. The peculiar role of viscoelasticity is examined. Naval architectural applications are reviewed.
