✦ Synopsis

Long hax-hke fibres were InJected at the boundary and centrehne of a turbulent pope flow of water and polymeric solution Pressure drop and mean velocity profiles were measured at various Reynolds numbers and mlectlon rates in order to study some mechamsttc aspects of drag reduction m these addrtlve systems Drag reduction m a fibre-water system IS attributed to a decrease m the momentum transfer m the turbulent-core region, whereas synergsm has been found to be a wall phenomenon
