Abstract
A laser-doppler instrument for measuring local velocity is used to study transition and turbulent pipe flow of a 50-WPPM aqueous solution of Polyox WSR 301 (polyethylene oxide) at the center of a 14-mm diam pipe; Reynolds numbers based on center line velocity range from 170 to 23,370; similar measurements are taken in water for comparison; addition of Polyox to water results in unsteady flow at Reynolds numbers for which the water flow is normally laminar; however, the longitudinal intensity of turbulence is not significantly altered from that in pure water.
