DEVELOPMENT OF A FLUID CONCENTRATED DISPERSION OF A WATER-SOLUBLE POLYMER CAPABLE OF REDUCING THE FRICTION OF WATER UNDER TURBULENT CONDITIONS.
Abstract
A method of using water soluble polymers to reduce the friction caused by turbulent flow of water was investigated by employing fluid, concentrated dispersions (slurries) of polymer in nonsolvent carriers. Prototype 10-percent slurries of various drag reducing polymers were injected into flowing turbulent water streams, and friction reductions as great as 49 percent were noted with mixing times as short as 1.5 seconds. Higher friction reduction was achieved at somewhat longer times. The system appears to be a very promising approach to applying drag reducing polymers to the waters around a ship hull. (Author)
