摘要：

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. diameter 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. © 1969, American Chemical Society.
