摘要：

Displacement experiments do not demonstrate significant persistence of a drag-reducing adsorbed film when a carboxymethylcellulose solution is displaced from a glass pipe by pure water in turbulent flow. The times needed to reach constant pressure gradient, upon which the existence of drag-reducing layers has been implied, can be greatly influenced by such factors as viscosity and the migration of drag-reducing fluid into the pressure tap connections. © 1969, American Chemical Society.
