THE EFFECT OF POLYMER ADDITIVES ON FRICTION PRESSURE DROP AND HEAT TRANSFER CHARACTERISTICS OF FLUIDS UNDER FORCED CONVECTION,
Abstract
A literature survey of the published information on the effects of polymer additives on friction pressure drop and heat transfer characteristics of fluids under forced convection has been carried out. The survey has shown a critical lack of systematic experimental data in both these areas. The existing analytical and semitheoretical predictions were found to be limited to purely viscous non-Newtonian fluids which do not exhibit the complex rheological behavior of the viscoelastic fluids. Absence of significant analytical and experimental work in the published literature was found to be justified due to a lack of understanding of the mechanism of drag reduction and due to the complex, and usually unstable, behavior of viscoelastic fluids.
