Two-component laser doppler velocimeter studies of submerged jets of dilute polymer solutions



Axisymmetric submerged jets of dilute solutions of poly(ethylene oxide) and polyacrylamide of high molecular weight were studied using a two-component laser Doppler velocimeter. At from 40–60 jet diameters from the source the small eddies are suppressed in the solutions studied. The behavior of the large eddies depends upon the elastic nature of the solution.
